Function Documentation

_POSIX_Semaphore_Delete()

void _POSIX_Semaphore_Delete

(

POSIX_Semaphore_Control *

the_semaphore

)

POSIX Semaphore Delete.

This routine supports the sem_close and sem_unlink routines.

_POSIX_Semaphore_Free()

RTEMS_INLINE_ROUTINE void _POSIX_Semaphore_Free

(

POSIX_Semaphore_Control *

the_semaphore

)

POSIX Semaphore Free.

This routine frees a semaphore control block to the inactive chain of free semaphore control blocks.
