- Product Overview
- ================
-
- The NetWare Btrieve Requester for UnixWare allows a Btrieve client
- application in a UnixWare environment to access Btrieve data on a
- NetWare Btrieve server. The Btrieve Requester uses the SPX Transport
- Layer Interface (TLI) and can establish or disconnect a connection
- with the Btrieve communications program BSPXCOM. BSPXCOM handles
- incoming requests to the Btrieve NLM from a remote source.
-
- The Btrieve Requester for UnixWare consists of a C interface object
- file, a set of archive libraries, and a set of shared-object libraries.
- Each set includes a library for the Btrieve Interface and a library
- for the Communications Interface.
-
- The following figure illustrates how UnixWare clients can access
- Btrieve data on a NetWare Btrieve server.

- The following sections describe the Btrieve Requester for UnixWare
- components.
-
-
- C Interface Object File
- -----------------------
-
- The C interface object file (UNXCBTRV.O) links a C application
- and maps a C interface to the Btrieve Requester interface.
-
-
- Btrieve Interface Library
- -------------------------
-
- The Btrieve Interface Library (LIBBTRV.A or LIBBTRV.SO) processes
- Btrieve requests, sending requests to and receiving responses from
- the Communications Interface Library.
-
- - LIBBTRV.A Archive Btrieve Interface Library
-
- - LIBBTRV.SO Shared-object Btrieve Interface Library
-
-
- Communications Interface Library
- --------------------------------
-
- The Communications Interface Library (LIBCOMM.A or LIBCOMM.SO) routes
- Btrieve requests to the specified server where the Btrieve NLM
- is located. It also receives responses from the NetWare server
- and returns them to the Btrieve Interface Library.
-
- - LIBCOMM.A Archive Communications Interface Library
-
- - LIBCOMM.SO Shared-object Communications Interface Library
-

- Using the Requester
- ===================
-
- The NetWare Btrieve v6.0 Requester for UnixWare is compatible with
- NetWare Btrieve v5.15, v6.0, and v6.1. In the case of NetWare
- Btrieve v6.1, however, the Btrieve v6.0 Requester for UnixWare
- does not provide full support for Btrieve v6.1 features.

- This section covers the following topics:
-
- - when to use archive and shared-object libraries
-
- - how to link the Btrieve Requester
-
- - how to configure the Btrieve Requester
-
- - how to establish Btrieve Requester connections
-
- - how to access files using the Btrieve Requester
-
- - which Btrieve operations are affected by the Btrieve Requester
-
-
- Archive and Shared-Object Libraries
- -----------------------------------
-
- You can use either the archive library set or the shared-object
- library set.
-
- - Use the archive library set (LIBBTRV.A and LIBCOMM.A) if you want
- to link the libraries with your program at link time.
-
- - Use the shared-object library set (LIBBTRV.SO and LIBCOMM.SO) if
- you want the libraries to be dynamically linked with your program
- at execution time.
-
-
- Requester Linking
- -----------------
-
- To use the Btrieve Requester for UnixWare, complete the follwing steps:
-
- 1. At the linker command line, link the UNXCBTRV.O file with your
- program.
-
- 2. Link your program with the following libraries (in the order given):
-
- LIBBTRV.A or LIBBTRV.SO
- LIBCOMM.A or LIBCOMM.SO
- LIBNWAPI.SO
- LIBNSL.SO
- LIBSOCKET.SO
- LIBDL.SO
-
- The following example illustrates how to link the Btrieve Requester
- for UnixWare:
-
- cc -c btrget.c
- cc -o btrget -L/home/mydir/univel/breq -L/home/mydir/univel/comm
- unxcbtrv.o btrget.o -lbtrv -lcomm -lnwapi -lnsl -lsocket -ldl
-
- where:
-
- -L/home/mydir/univel/breq Indicates the location of libbtrv.a.
-
- -L/home/mydir/univel/comm Indicates the location of libcomm.a.
-
- btrget.c Specifies your program file.
-
- btrget.o Specifies the object file for btrget.c.
-
-
- NOTE: You can place UNXCBTRV.O in your working directory. However,
- if you want to place UNXCBTRV.O in another directory, specify
- the file's location.
-
- For shared-object libraries ending with the .SO extension, you need to
- set the environment variables under the Bourne shell as follows:
-
- LD_LIBRARY_PATH=/home/mydir/univel/breq:/home/mydir/univel/comm export
- LD_LIBRARY_PATH
-
-
- Requester Configuration Options
- -------------------------------
-
- You do not need to set any configuration options to specify the size
- of the data message buffers. The Btrieve Requester for UnixWare
- dynamically expands the data message buffer to pass records between
- Btrieve and the application. The Btrieve Requester for UnixWare
- also dynamically expands the Server Router Table that is used for
- routing the Btrieve requests to the specified server.
-
-
- Requester Connection and Termination
- ------------------------------------
-
- A UnixWare client can connect to a maximum of 50 servers. The Btrieve
- Requester for UnixWare automatically terminates all the connections
- that are left open when an application exits. However, the files
- that are left open when an application exits remain open until a
- Btrieve Stop operation is issued.
-
-
- File Access
- -----------
-
- There are no drive mappings in UnixWare. You must log in to the
- server and initiate authentication with the server in order to
- access files or directories on it. You can use the NetWare Access
- Utility (NAU) to log in to the server.
-
- You cannot use relative paths or simple filenames. You must use the
- full pathname because of the limitation imposed by the NetWare C
- Interface.
-
-
- Btrieve Operations
- ------------------
-
- The Btrieve Requester for UnixWare affects the following Btrieve
- operations:
-
- - Get Directory: This operation can return only the current
- directory. It ignores the logical disk drive specified in the key
- number parameter.
-
- - Set Directory: For this operation, you must specify the path
- according to the UnixWare pathname specification.
