Creating NamedPipes

Hello Everybody,

I have a Win32 Server Program which creates many pipes.I know that, name of the pipe will be having a standard format and cannot be changed.Pipe name creation will be as follows,

LPTSTR lpszPipename = TEXT(\\\\.\\pipe\\SamplePipe);

hPipe = CreateNamedPipe(lpszPipename, PIPE_ACCESS_DUPLEX,PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_WAIT, PIPE_UNLIMITED_INSTANCES,BUFSIZE, BUFSIZE,0,NULL);

Now my question is, can we create a named pipe dynamically, means creating a pipe during run time.

Hope my qustion is somewhat clear.

Shiva..

The code you showed does exactly what you asked: it creates (or, at least, tries to create) a named pipe during run time.

BTW, I don't know a way to create a named pipe before run time (in design time) nor after the run time. :rolleyes:

That's new to me. :) The name of the pipe can be changed alright once both server and client sides agree on new name. ;)

No your question is not. Actually the code you quoted already is dynamic pipe creation. So what made you think it's not dynamic? or it's not a creation?
