NAME
intro
- introduction to the C libraries
DESCRIPTION
This section provides an overview of the C
library functions, their error returns and other
common definitions and concepts.
Most of these functions are available from the C library,
libc
Other libraries, such as the math library,
libm
must be indicated at compile time with the
-l
option of the compiler.
The various libraries (followed by the loader flag):
- libcPqFllNsArc
-
Standard C library functions.
When using the C compiler
cc(1),
it is not necessary
to supply the loader flag
-l c
for these functions.
There are several `libraries' or groups of functions included inside of
libc:thestandard
I/O
routines,
database routines,
bit operators,
string operators,
character tests and character operators,
des encryption routines,
storage allocation, time functions, signal handling and more.
-
libcurses
( -l curses
-l termcap
-
- Terminal independent screen management routines
for two dimensional non-bitmap display terminals.
(See
curses(3).)
- libcompatPqFllNsArcompat
-
Functions which are obsolete but are available for compatibility with
BSD 4.3
In particular,
a number of system call interfaces provided in previous releases of
BSD have been included for source code compatibility.
Use of these routines should, for the most part, be avoided.
The manual page entry for each compatibility routine
indicates the proper interface to use.
- liblPqFllNsArl
-
The library for
lex(1).
- libmPqFllNsArm
-
The math library,
libm
- libtermcapPqFllNsArtermcap
-
The terminal independent operation library package. (See
termcap(3).)
- libyPqFllNsAry
-
The library for
yacc(1).
