- 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.
