FILE* and streams

Hello all,
   I'm making use of a static library that makes use of stdout and stderr as input to different functions that require a FILE* as a parameter.  I would like to make use of these functions, but do not want to create a temporary, ( or permanent for that matter ), file on the drive to make use of the functions.  What can I do to pass a stream into this function so that I can read the output from the function?

Thanks much.

You could use a pipe.  Depending on the OS, it could be as simple as opening a file named "\\.\\pipe\\MyPipe".

Hi grg99.  The OS is windows, (most likely 2K, XP and 2003, but could also be 9x).  Would the pipe work on the Windows OSs?

Thanks much.

Also, if so, where can I find documentation on how to use it?

Thanks again.

Of course you can use pipes on Windows. Take a look here http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ipc/base/pipes.asp

Note that pipes are kinda shaky-- the semantics of multiple pipe readers are very fuzzy.  Also Windows 95/98 are only half-assed-- they can be pipe clients but not servers.  Yet another intentional cripling, thanks MSoft.

I'd try using a temporary file, much easier and works on all OS's.
