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 possible.

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.
