Oh. I see what you asked. But that is not what PIPE_BUF is. Solaris does know the size of a pipe file - fstat() on the open file descriptor returns a struct stat with st_size in bytes. This is the amount of data waiting to be read from the pipe. Other versions of unix do not support this extension to stat functionality.

PIPE_MAX is 'how many bytes can I stuff into a pipe with a single call to write, and still have the call complete atomically'

It is not clear to me which one you want. But you have choices.
