- Nmpipe.c is a simple, console named pipe sample demonstrating the "thread per
- client" method of a named pipe client/server architecture. This sample
- application demonstrates how to create and connect clients from a server
- application, and how to wait for and connect to pipes from a client
- application.
- To compile the application for simultaneous reading and writing, uncomment the
- "#define OVERPAPED_IO TRUE" statement in nmpipe.c. For one-way pipe operations,
- uncomment the "#define OVERLAPPED_IO FALSE" statement.
- The sample can be started either as a server or as a client. To start the
- sample as the server, use the /s parameter. To start the sample as a client,
- use /c. Following either /s or /c should be a string to write to the pipe.
- Strings with spaces should be quoted. Following the string is an optional
- parameter that specifies the full name of the pipe to create or connect to. If
- none is given, a default pipe name is used.
- For example, to start a server and client:
- nmpipe /s "hello from the server " \.pipetestpipe
- nmpipe /c client \.pipetestpipe
- If OVERLAPPED_IO is defined as TRUE, this will cause the client and server to
- write their respective strings to each other over the named pipe. If
- OVERLAPPED_IO is defined as FALSE, then the client will only write and the
- server will only read.
- Note that Windows 95 cannot create named pipes, so the /s (run as server) flag
- will cause errors on the CreateNamedPipe call under Windows 95. In addition,
- Windows 95 does not support overlapped I/O on named pipes; if the app is
- compiled with OVERLAPPED_IO defined as TRUE, errors will result from the
- CreateFile calls, which use the FILE_FLAG_OVERLAPPED flag in this case. So be
- sure to define OVERLAPPED_IO as FALSE before compiling on Windows 95.
