Well, at first libc is organized in separated dirs for ANSI/POSIX/DOS, that
could help you. Another interesting thing is to have the libc.info file from
Linux in your hard-disk to check if the function exists in Linux (I have it).
And you can use as last resort the information from the TurboC help.

That's a good idea, I look the Linux help all the time to check it ;-)
