Current state of some POSIX calls?

[Martin.Rauh@RSD.rohde-schwarz.com]

Hi,

does anyone know the current state of implementation of the following
POSIX-calls in glibc:
- shm_open for shared memory
- sem_open for named semaphores
- sem_wait with timeout
- all the other POSIX-calls for conditional objects with timeout

The documentation does not say much about that.

Thanks in advance,

Martin
