I'm trying to use POSIX named semaphores on -current.
sem_open()/sem_close()/sem_unlink() calls. Looks like it works just fine. At
least with my simple client/server tests and according to kern/uipc_sem.c
code. On the other hand, man pages for -current says that:
The sem_open(), sem_close(), and sem_unlink() functions are not supported by
sem_open() returns SEM_FAILED and sets errno to indicate an error. sem_close()
and sem_unlink() return -1 and set errno to indicate an error.
Is there any serious reason no to publish information about POSIX named
semaphores or man pages just a bit out of date ?
ps: My thanks to Jason R. Thorpe for his work :) It's really usefull API
