<function>sem_acquire</function> blocks (if necessary) until the
|
|
semaphore can be acquired. A process attempting to acquire a
|
|
semaphore which it has already acquired will block forever
|
|
if acquiring the semaphore would cause its maximum number
|
|
of semaphore to be exceeded.
|
|
<parameter>sem_identifier</parameter> is a semaphore ressource,
|
|
obtained from <function>sem_get</function>.

After processing a request, any semaphores acquired by the
|
|
process but not explicitly released will be released automatically
|
|
and a warning will be generated.
