- OVERVIEW
-
- The QBWARE/Net libraryy allows you to develop code in Basic or
- Quickbasic that can run in an IPX/SPX or NetBios environment
- without change. The library contains the following FUNCTIONs.
-
-
- NetStart%
- NetCall%
- NetListen&
- NetSend%
- NetReceive%
- NetConverse%
- NetBroadcast%
- NetHangUp%
- NetStop%
- NetLastError%
-
- These FUNCTIONs can be used to establish peer-to-peer communications
- with other workstations on a Local Area Network.
-
-
- USAGE
-
- NOTE THAT YOU MUST USE THE /O OPTION WHEN COMPILING PROGRAMS USING
- QBWARE/Net.
-
- The library contains the following files:
-
- NETWORK.BI This file should be included in your program using
-
- REM $INCLUDE: 'NETWORK.BI'
-
- It contains PROTOTYPE statements for each function as
- well as TYPE declarations for the data structures by
- the library.
-
- IPXLIBxx.OBJ This file should be linked with your application
- program. It contains the high-level interface to
- the IPX routines used to communicate across the
- network. There are language dependent versions of
- this file IPXLIBBC.OBJ is used for BASIC PDS v7.1 and
- IPXLIBQB.OBJ is to be used with Quickbasic v4.5.
-
- NETWORK.LIB This file contains the low-level protocol specific
- routines used to communicate across the network.
-
- PILEBC.BAT Sample compile batch job for BASIC PDS v7.1. It is
- included for illustration purposes. If you elect to
- use this batch file to compile your programs, please
- modify the pathnames to fit your development
- environment.
-
- PILEQB.BAT Sample compile batch job for Quickbasic. It is
- included for illustration purposes. If you elect to
- use this batch file to compile your programs, please
- modify the pathnames to fit your development
- environment.
-
-
- FUNCTIONS
-
- DECLARE FUNCTION NetStart% (St AS NetStation)
-
- NetStart initializes all Network communications buffers and
- determines how many concurrent requests can be handled. The
- NDSessions variable contains the number of concurrent requests.
- It should be initialized before calling NetStart. If not
- specified, it defaults to 12. Each session requires about
- 600 bytes of storage. Your local workstation ID is returned
- in the variable St.
-
-
-
-
- DECLARE FUNCTION NetCall% (Target AS NetStation)
-
- NetCall establishes communications with another station on the
- network. In a connectionless environment like IPX, this call
- is meaningless and always returns 0. It should be used, however,
- to insure compatibility with connection-oriented services like
- NetBios and SPX. The Target must be the network name of the
- machine that you are trying to establish a connection to.
-
-
-
-
- DECLARE FUNCTION NetListen& ()
-
- NetListen starts a listen session and enables your workstation to
- receive messages from other stations on the network. You cannot
- receive messages unless you first issue a NetListen. This should
- generally be the first thing your program does after calling
- NetStart. If you expect to receive more than one message at a
- time or communicate with more than one station at a time, you
- should issue multiple NetListen calls. Each time you execute
- this call, one session is permanently reserved. Because of this,
- you should never execute this call more than the number in NDSession
- less 4. In other words, do not execute NetListen more than
- NDSession - 4 times.
-
-
-
-
-
- DECLARE FUNCTION NetSend% (Target AS NetStation, Message AS NetMsg)
-
- NetSend sends a message to the target station. Note that the Message
- cannot exceed 512 characters.
-
-
-
-
-
- DECLARE FUNCTION NetReceive% (Source AS NetStation, Message AS NetMsg)
-
- NetReceive checks to see if any Network messages have been received.
- If a message is received, the sending station is returned in Source.
- You should regularly call NetReceive if you expect to receive messages
- from many stations.
-
-
-
-
-
- DECLARE FUNCTION NetConverse% (Target AS NetStation, SendMsg AS NetMsg, RecvMsg AS NetMsg)
-
- NetConverse send a message to the target station and waits up to 5
- seconds for a response. In a connectionless service like IPX, this
- service sends a message and waits for the next response from anyone.
- It should not be used if you are expecting message from multiple
- stations. The NDTimeOut& parameter can be used to vary the timeout
- length.
-
-
-
-
-
- DECLARE FUNCTION NetBroadcast% (NetHandle AS Long, Message AS NetMsg)
-
- NetBroadcast sends a message to anyone on the network who is
- listening. A broadcast will generally work only on the local
- network and usually does not cross a bridge. In the IPX
- implementation, you can initialize NDNetNum$ to the appropriate
- network number before making this call and the broadcast will
- be routed to that network.
-
-
-
-
-
-
- DECLARE FUNCTION NetHangUp% (Target AS NetStation)
-
- NetHangUp terminates the connection between your workstation
- and the target station. In a connectionless service like IPX,
- this call is for compatibility only but should always be used
- to insure compatibility with the connection-oriented services
- like SPX and NetBios.
-
-
-
-
-
-
- DECLARE FUNCTION NetStop% ()
-
- NetStop frees up the communication buffers and control blocks.
- These areas are then returned to Basic for its use.
-
-
-
-
-
- DECLARE FUNCTION NetLastError% ()
-
- This function returns the extended error code after a call
- fails. Anytime a FUNCTION returns a -1, call NetLastError
- to determine a more detailed cause for the failure.
-
- Possible values are:
-
- IPX implementation
-
- 249 ECB cannot be cancelled
- 250 Destination node not found
- 254 Socket Table is full
- 255 Socket is already open
- Listening Socket does not exist
- ECB is not in use
-
