Hi folks,

I'm looking for some documentation about the cygwin spawn use, or a recommendation of a package that has had fork/exec replaced by spawn that I can review to see how someone else did it. Preferably less intimidating than gcc, and which uses pipes for IPC between parent and child. 

In particular, the code I'm looking to patch does a typical fork/exec and uses 2 pipes to communicate bi-directionally parent to child. The pipes are throwing me off as to if cygwin spawn is usable.

I've been through the spawn.cc code, and see spawn_guts has a concept of __stdin and __stdout, but I don't see those params used by any of the spawn functions. 

Any help or pointers to code or docs appreciated. 

Thank you,
Devin Nate
