DESCRIPTION
     These routines are described in the ANSI C, POSIX,  BSD  and
     System  V  manual  sections  2  and  3.   The interfaces are
     preserved and present in all libast implementations.   Where
     conflicts  exist the POSIX syntax and semantics are implied.
     The appropriate error value is returned and errno is set  to

     EINVAL  when emulation is either too expensive or not possi-
     ble.

CAVEATS
     If you #undef foo and then call foo you may end up with  the
     local implementation of foo, and then you get what you payed
     for.
