ΓòÉΓòÉΓòÉ 2. Introduction ΓòÉΓòÉΓòÉ
The IBM* Library Manager (also referred to as LIB in this reference) lets you
create and maintain libraries of object code.
Library files are given the extension of ".LIB" (as in MYLIB.LIB). High
Performance File System (HPFS) file names are also supported as long as the
file names ends with ".LIB" (as in MYLIBRARYFILE.NEW.LIB).
LIB works with standard libraries and OS/2* import libraries. It does not work
with Dynamic Link Libraries (DLL).
Use LIB to:
o Create a new library
o Add, delete, or replace modules in a library
o Copy object modules in a library to object files
o List the contents of a library
ΓòÉΓòÉΓòÉ 3. Running LIB ΓòÉΓòÉΓòÉ
Run LIB by typing "LIB" at the operating system prompt.
Parameters can be supplied by one of three methods:
1. Enter them directly on the command line.
2. Respond to prompts.
3. Put them in a text file called a response file and specify the file name
after the LIB command.
To enter more commands than can be conveniently entered on one line, type an
ampersand (&) at the end of the line and press Enter to extend the command
field to a new line. The ampersand can be used with all three input methods.
You can press Ctrl+C or Ctrl+Break at any time during a LIB run to return to
the operating system. Interrupting LIB before completion restores the library
from the backup.
Note:
o When started, LIB makes a backup copy of the original library in case it is
interrupted or a mistake is made. Make sure you have enough disk space for
both your original library and the modified copy.
o The library must end with the extension ".LIB". If an extension is not
specified, the default extension, ".LIB", will be appended. HPFS file names
are supported. Hence, MYLIBRARYNAME.NEW.LIB is still a valid library. Note
that this implies that MYLIBRARYNAME.NEW refers to MYLIBRARYNAME.NEW.LIB.
o If you enter an input library name and follow it immediately with a semicolon
(;), LIB performs a consistency check on the library and takes no other
action.
ΓòÉΓòÉΓòÉ 3.1. Using the Command Line ΓòÉΓòÉΓòÉ
You can specify all the input LIB needs on the command line. The syntax of the
command line is:
LIB [options] inlibrary [commands] [[,listfile] [, outlibrary]] [;]
inlibrary The input library to be modified.
options Options that affect the way LIB runs.
commands Commands used to add, delete, replace, copy, and move modules
within the library.
listfile The name for a listing file. If you don't specify a name, no
file is created.
outlibrary The output library created from the input library. If you
don't specify an output library, your input library is
replaced with the modified version (see below).
Commas are used to separate commands and options. The semicolon (;) is used to
mark the end of the command line.
ΓòÉΓòÉΓòÉ 3.2. Using LIB Prompts ΓòÉΓòÉΓòÉ
If you don't provide input to LIB on the command line, LIB prompts you for the
information it needs by displaying the following messages, one at a time:
Prompt Enter
Library name
Name of the input library to be modified.
Operations
Commands to modify the library. If no operations are
specified, the input library is unchanged.
List file
Name for a listing file If no listing file is specified, no
listing file is created.
Output library
Name of the output library to be created from the input
library. If no output library is specified, LIB modifies the
input library.
Enter the same information that you would enter when using the LIB command
line.
Notes
o LIB waits for you to respond to each prompt before displaying the next
prompt. If you notice that you have entered an incorrect response to a
previous prompt, press Ctrl+C or Ctrl+Break to exit LIB and begin again.
o A file name must be entered at the Library name: prompt. To choose a default
response for any of the other prompts, press Enter. To choose default
responses for all remaining prompts, type a semicolon (;) and press Enter.
ΓòÉΓòÉΓòÉ 3.3. Using a LIB Response File ΓòÉΓòÉΓòÉ
To provide input to LIB with a response file, type:
LIB @responsefile;
The field responsefile is the name of a file containing the same information
that can be specified on the command line.
In a sense, a response file extends the command line to include everything in
the response file. To split input to LIB between the command line and a
response file, put part of your input on the command line and specify a
response file (preceding the response file name with the at sign (@)). The
response file name can be any valid OS/2 file. To use special characters such
as a space or the @ symbol, the filename must be enclosed in quotes.
LIB responds to input you place in a response file just as it does to input you
enter on a command line or after a prompt. Using a newline character in the
response file is the equivalent of pressing the Enter key after a LIB prompt.
A response file uses one text line for each prompt. To extend a LIB command to
multiple lines, end each line except the last with an ampersand (&). Responses
must appear in the same order as the prompts. If a response for one of the
prompts does not appear, the default is used.
Use a response file for:
o Complex and long commands you type frequently
o Strings of commands that exceed the limit for command line length.
ΓòÉΓòÉΓòÉ <hidden> Specifying LIB Parameters - Examples ΓòÉΓòÉΓòÉ
This panel shows you examples of each method for specifying parameters to LIB.
In the examples, the following operations create a new library, NEWLIB.LIB, and
its listing file, NEWLIB.LST, from the existing MYLIB.LIB library. MYLIB.LIB is
unchanged, but NEWLIB.LIB has these changes:
o The contents are case-insensitive.
o The module TIM is deleted.
o The object file SIMON.OBJ is appended as an object module with the name
SIMON.
o The existing module KEHM is deleted and is replaced by a new KEHM which is
appended after SIMON.
o The module LAM is copied into an object file named LAM.OBJ.
Command Line Method
At the operating system prompt, enter the following two lines.
LIB /I MYLIB, SIMON-TIM-+KEHM &
*LAM, NEWLIB.LST, NEWLIB;
LIB Prompts Method
To have LIB prompt you for input, enter LIB with no parameters.
Library name: /I MYLIB
Operations: +SIMON-TIM-+KEHM &
Operations: *LAM
List file: NEWLIB.LST
Output library: NEWLIB
Response File Method
First, create a response file with the following contents.
/I MYLIB
+SIMON-TIM-+KEHM &
*LAM
NEWLIB.LST
NEWLIB
Then, assuming the name of the response file is response.fil, invoke LIB with:
LIB @RESPONSE.FIL;
Note that the lines in the response file match the entries you would have made
with the prompting method. Even the ampersand character (&), the continuation
character, is used in the same way.
ΓòÉΓòÉΓòÉ 4. Creating a New Library ΓòÉΓòÉΓòÉ
To create a new library file, give the name of the library file you want to
create in the inlibrary field on the command line (or at the Library name:
prompt when using LIB prompts).
Note: A library file is automatically created if the library file name you
specify is immediately followed by a command, comma, or semicolon. In this
case, the prompt does not appear.
If the name you specify for the new library file already exists, LIB assumes
that you want to modify the existing file.
When you give the name of a file that does not currently exist, LIB displays
the following prompt:
Library does not exist. Create library? (y or n)
Type y to create the file; type n to terminate the LIB run. If you specified an
extension other than .LIB, LIB will try to append the .LIB extension to the
entire file name. If a library name is not entered, LIB will prompt you with
Library name:.
ΓòÉΓòÉΓòÉ 5. Modifying a Library ΓòÉΓòÉΓòÉ
You can use LIB to alter the contents of any object code library. For example,
if you work with high level language libraries, you may want to replace a
standard routine with your own version of the routine. You may also want to add
a new routine to the standard library so that your routine is available along
with the standard routines.
To modify an existing library file, give the name of the library file you want
to modify in the inlibrary field of the command line (or at the Library name:
prompt when using LIB prompts).
In the command field, enter one or more commands to add, delete, or replace
modules in the input library. Each command consists of a command character
immediately followed by the name of the module or object file. Note that the
Add command can be used to combine libraries as well as to add object files to
a library. See:
Add Command (+)
Delete Command (-)
Replace Command (-+)
LIB creates a backup file of the library being modified if it already exists.
This backup file has the same name as the original library with ".BAK" as the
extension.
ΓòÉΓòÉΓòÉ 6. Copying Object Modules to Object Files ΓòÉΓòÉΓòÉ
To copy a module from a library file to an object file, give the name of the
library file in the inlibrary field on the command line (or at the Library
name: prompt when using LIB prompts).
The command field on the command line allows you to move or copy modules.
Command Action
copy (*) LIB copies the module to an object file and retains the module in the
library.
move (-*) LIB copies the module to an object file and deletes the module from
the library.
ΓòÉΓòÉΓòÉ 7. Listings ΓòÉΓòÉΓòÉ
Listings give you the exact names of modules and public symbols, allowing you
to inspect the contents within a library.
To generate a listing file, enter the following on the command line (or at the
appropriate LIB prompt):
o The name of the library file in the inlibrary field
o The name of the listing file in the listfile field
When generating a listing file, the amount of detail can be varied. The level
of detail is specified with the
/Listlevel:n
option, with three different levels being available.
Level 1 is the default. It is the fastest to generate and contains the least
amount of information. All modules are listed in order of occurrence. For each
module, the level 1 option:
1. Shows the relative position and size of each module.
2. Lists all the public symbols defined in the module.
3. Lists all external symbols which must be resolved at link time.
Level 2 contains all the information of level 1. In addition, for each external
symbol, level 2 shows which module in the library contains the required public
symbols for resolving at link time. This can be overridden if a module is
linked to another module that already contains the symbol.
Level 3 contains all the information of level 2. In addition, Level 3 displays
the technical characteristics of the library. This option also contains a dump
of the extended dictionary. This is useful to determine which modules will be
implicitly linked in whenever a particular module is linked in.
Note: If you are using the IBM C/C++ Tools product, definitions with mangled
names will be listed with the demangled form in brackets.
Sample Cross Reference Listing
LIB /LISTLEVEL:2 NEWLIB, NEWLIB.LST;
The command above directs LIB to place a listing of the contents of NEWLIB.LIB
into the file NEWLIB.LST. No path specification is given for NEWLIB.LST. By
default, the file created is put in the current directory.
ΓòÉΓòÉΓòÉ <hidden> Listing Example ΓòÉΓòÉΓòÉ
The syntax used to generate a listing file with level 3 option is:
LIB /L:3 NEWLIB, NEWLIB.LST;
This command generates the following listing file called NEWLIB.LST:

ΓòÉΓòÉΓòÉ 8. Commands ΓòÉΓòÉΓòÉ
LIB commands are used to manipulate modules in a library. A single LIB run uses
multiple commands in any order.
Each command consists of a one or two character command symbol immediately
followed by the name of the module or file that is the subject of the command.
For example,
+EFREM.OBJ
adds the EFREM.OBJ object file to a library as EFREM.
Command Action
[+] Adds an object file or library to a library
- Deletes a module from a library
-+ Replaces a module in a library
* Copies a module from a library to an object file
-* Moves a module (copies the module and then deletes it)
Notes
o If you want to enter more commands than can be conveniently entered on one
line, type an ampersand (&) and press Enter at the end of the line. This
extends the command field to the next line.
o When processing commands, LIB processes all copy commands first. LIB then
processes the deletions and processes the additions last.
o LIB never makes changes to your input library while it runs; it copies the
library and makes changes to that copy. However, if you don't specify an
output library, LIB overwrites the input library with the modified copy at
the end of normal processing. See Using the LIB Command Line for more
information.
ΓòÉΓòÉΓòÉ 8.1. Add Command (+) ΓòÉΓòÉΓòÉ
Use the add command to add an object module or library to a library. The add
command is issued using the plus (+) sign or leaving a blank space.
Adding an Object Module to a Library
Type the name of the object file to be added immediately after the plus sign.
The ".OBJ" extension may be omitted.
LIB uses the base name of the object file as the name of the object module in
the library. For example, if the object file B:\CURSOR.OBJ is added to a
library file, the name of the corresponding object module is CURSOR.
Object modules are always added to the end of a library file.
Combining Two Libraries
Give the name of the library file to be added, including the ".LIB" extension,
immediately after the plus sign (+). A copy of the contents of that library is
added to the library file being modified. If both libraries contain a module
with the same name, LIB ignores the second module with that name.
LIB adds the modules of the library to the end of the library being changed.
Note that the added library still exists as an independent library because LIB
copies the modules without deleting them.
Examples
LIB MYLIB +EFREM;
The command above adds the file EFREM.OBJ to the library MYLIB.LIB.
LIB NEWLIB +KAREN.LIB;
The command above adds the contents of the library KAREN.LIB to the library
NEWLIB.LIB. The library KAREN.LIB is unchanged after this command is executed.
ΓòÉΓòÉΓòÉ 8.2. Delete Command (-) ΓòÉΓòÉΓòÉ
Use the delete command (-) to delete an object module from a library. After the
minus sign, give the name of the module to be deleted. Module names do not have
path names or extensions.
Example
LIB MYLIB -EFREM;
The command above deletes the module EFREM from the library MYLIB.LIB.
ΓòÉΓòÉΓòÉ 8.3. Replace Command (-+) ΓòÉΓòÉΓòÉ
Use the replace command (-+) to replace a module in a library. Following the
symbol, give the name of the module to be replaced.
To replace a module, LIB performs the following steps:
1. Deletes the existing module
2. Searches the current directory for the ".OBJ" file with the same file name
as the deleted module
3. Appends to the library a copy of the object file with the original module
name
Example
LIB MYLIB -+EFREM;
The command above replaces the module EFREM in the MYLIB.LIB library with the
contents of EFREM.OBJ from the current directory. The file EFREM.OBJ in the
current directory is not altered.
ΓòÉΓòÉΓòÉ 8.4. Copy Command (*) ΓòÉΓòÉΓòÉ
Use the copy command (*) to copy a module from the library into an object file
of the same name. The module remains in the library.
When LIB copies the module to an object file, it adds the ".OBJ" extension to
the module name and places the file in the current directory. If a file with
this name already exists, LIB overwrites the existing ".OBJ" file.
Example
LIB MYLIB *EFREM;
The command above copies the module EFREM from the MYLIB.LIB library to a file
called EFREM.OBJ in the current directory. The module EFREM in MYLIB.LIB is not
altered.
ΓòÉΓòÉΓòÉ 8.5. Move Command (-*) ΓòÉΓòÉΓòÉ
Use the move command (-*) to copy an object module from the library file to an
object file. The object module is then deleted from the library file. This
operation is equivalent to copying the module to an object file, then deleting
the module from the library.
Example
LIB MYLIB -*KEELING;
The command above moves the module KEELING from the MYLIB.LIB library to a file
called KEELING.OBJ in the current directory. Upon completion of this process,
MYLIB.LIB no longer contains the module KEELING.
ΓòÉΓòÉΓòÉ 9. Options ΓòÉΓòÉΓòÉ
Usage Notes:
o Option characters are not case sensitive; /H and /h are equivalent.
o The characters in brackets can be omitted; /H and /HELP are equivalent.
o Unless otherwise specified, most options and commands need only the first
letter of their names to be used.
The following is a summary of LIB options:
Option Action
/? or ? or /H[ELP] Display Help
/I[GNORECASE] Turn Case Sensitivity Off
/NOE[XTDICTIONARY] Disable Generation of Extended Dictionary
/NOI[GNORECASE] Turn Case Sensitivity On
/NOL[OGO] Suppress LIB Banner
/Q[UIET] Suppress LIB Banner
/P[AGESIZE] Set Library Page Size
/L[ISTLEVEL] List Current Contents of Library
ΓòÉΓòÉΓòÉ 9.1. /I Option ΓòÉΓòÉΓòÉ
Turn Case Sensitivity Off (/I)
Syntax: /I[GNORECASE]
Purpose: Turns off case sensitivity for symbols
By default, case sensitivity is off. Use this option when you are combining a
library that was created with case sensitivity on (using the /NOI option) with
others that are not case sensitive. The resulting library is not case
sensitive.
ΓòÉΓòÉΓòÉ 9.2. /NOE Option ΓòÉΓòÉΓòÉ
Disable Generation of Extended Dictionary (/NOE)
Syntax: /NOE[XTDICTIONARY]
Purpose: Disables generation of extended dictionary
The extended dictionary is an optional part of the library that increases
linking speed. However, using an extended dictionary requires more memory. The
space reserved for the extended dictionary is limited to 64K, no more can be
allocated. If LIB reports an out-of-memory error, you may want to use this
option. As an alternative, you can split large libraries into smaller libraries
to use in linking.
ΓòÉΓòÉΓòÉ 9.3. /NOI Option ΓòÉΓòÉΓòÉ
Turn Case Sensitivity On (/NOI)
Syntax: /NOI[GNORECASE]
Purpose: Turns on case sensitivity
By default, case sensitivity is off (/I option). Using this option allows
symbols that differ only in case, such as Sine and SINE, to be included as
separate symbols in the same library.
Note that when you create a library with the /NOI option, LIB marks the library
internally to indicate that /NOI is in effect. If you combine multiple
libraries, and any one of them is marked /NOI, then the output library is
marked /NOI.
ΓòÉΓòÉΓòÉ 9.4. /P Option ΓòÉΓòÉΓòÉ
Set Library Page Size (/P)
Syntax: /P[AGESIZE]: n
Purpose: Sets library page size
This option specifies the library page size of a new library or changes that of
an existing library. The new page size n must be an integer value representing
a power of 2 between the values 16 and 32,768.
A library's page size affects the alignment of modules stored in the library.
Modules are always aligned to start at a position that is a multiple of the
page size (in bytes) from the beginning of the file. The default page size for
a new library is 16 bytes. For an existing library, the default is its current
page size.
Because of LIB's indexing technique, the larger the page size, the more modules
a library can hold. Each module requires an average of n/2 bytes of storage
space. Therefore, you should use a small page size unless you need to put a
very large number of modules in a library.
Another consequence of LIB's indexing technique is that the page size limits
the size of the library file to n * 65,536. For example, the option /P:16
limits the size to 1 megabyte (16 * 65,536 bytes).
ΓòÉΓòÉΓòÉ 9.5. / ? or ? or /H Option ΓòÉΓòÉΓòÉ
Display Help
Syntax: /H[ELP]
or
/?
or
?
Purpose: Displays help on LIB
A brief summary of LIB syntax is displayed.
ΓòÉΓòÉΓòÉ 9.6. /NOL or /Q Option ΓòÉΓòÉΓòÉ
Suppress LIB Banner
Syntax: /NOL[OGO] or /Q[UIET]
Purpose: Suppresses the LIB copyright notice.
This option suppresses the banner message when LIB is started. It can be used
in batch files.
ΓòÉΓòÉΓòÉ <hidden> Library ΓòÉΓòÉΓòÉ
A library is an organized collection of object code which contains functions
and data that are already assembled or compiled. Once an object file is
incorporated into a library, it becomes an object module.
Libraries are used to:
o Support high level languages. Most compilers include libraries to perform
standard operations, such as input/output and floating-point mathematics.
When your program refers to a library routine, the compiler and linker
combine the library routine with your program.
o Perform complex and specialized activities, such as database management or
advanced graphics. You can use your own libraries or specialized libraries
supplied by a vendor.
o Support your own work. If you have created routines that you use with a
variety of programs, you may want to consolidate these routines into a
library. You can then link to one library.
ΓòÉΓòÉΓòÉ <hidden> Output Library ΓòÉΓòÉΓòÉ
If you specify a file in outlibrary, LIB creates a new output file with the
modifications and leaves your input file intact. Otherwise, LIB replaces your
input file with the modified file. In the latter case, a backup of your
original input file is stored in the current directory with the file name
extension ".BAK".
ΓòÉΓòÉΓòÉ <hidden> Object File ΓòÉΓòÉΓòÉ
An object file is produced by a compiler or assembler from one or more source
files. An object file has an extension of ".OBJ". (as in "MYPROJ.OBJ"). In
LIB, HPFS file names are also supported as long as the file name ends with
".OBJ" (as in "MYOBJECTFILE.NEW.OBJ").
ΓòÉΓòÉΓòÉ <hidden> Object Module ΓòÉΓòÉΓòÉ
The object module is a self-contained unit within a library of precompiled or
preassembled routines. When individual object files are combined into a single
library file, they become object modules.
In LIB, an object module is referred to by its name, without a file extension.
For example, assume that the object file KEELING.OBJ is inserted into a
library. It then becomes an object module and is simply referred to as KEELING.
