APR::ThreadMutex - Perl API for APR thread mutexes

  use APR::ThreadMutex ();

  my $mutex = APR::ThreadMutex->new($r->pool);
  $mutex->lock;
  $mutex->unlock;
  $mutex->trylock;

APR::ThreadMutex interfaces APR thread mutexes.

APR::ThreadMutex provides the following functions and/or methods:

APR::ThreadMutex also provides auto-generated Perl interface for a few other methods which aren't tested at the moment and therefore their API is a subject to change. These methods will be finalized later as a need arises. If you want to rely on any of the following methods please contact the the mod_perl development mailing list (maillist::dev) so we can help each other take the steps necessary to shift the method to an officially supported API.

META: Autogenerated - needs to be reviewed/completed

Destroy the mutex and free the memory associated with the lock.

  $mutex->DESTROY();

obj: $mutex ( APR::ThreadMutex object (docs::2.0::api::APR::ThreadMutex) )

the mutex to destroy.

ret: no return value

since: subject to change

META: Autogenerated - needs to be reviewed/completed

Acquire the lock for the given mutex. If the mutex is already locked, the current thread will be put to sleep until the lock becomes available.

  $ret = $mutex->lock();

obj: $mutex ( APR::ThreadMutex object (docs::2.0::api::APR::ThreadMutex) )

the mutex on which to acquire the lock.

ret: $ret ( integer )

since: subject to change

Create a new mutex

  my $mutex = APR::ThreadMutex->new($p);

obj: APR::ThreadMutex ( class name )

arg1: $p ( APR::Pool object (docs::2.0::api::APR::Pool) )

ret: $mutex ( APR::ThreadMutex object (docs::2.0::api::APR::ThreadMutex) )

since: subject to change

META: Autogenerated - needs to be reviewed/completed

META: should probably be renamed to pool(), like all other pool accessors

Get the pool used by this thread_mutex.

  $ret = $obj->pool_get();

obj: $obj ( APR::ThreadMutex object (docs::2.0::api::APR::ThreadMutex) )

ret: $ret ( APR::Pool object (docs::2.0::api::APR::Pool) )

apr_pool_t the pool

since: subject to change

META: Autogenerated - needs to be reviewed/completed

Attempt to acquire the lock for the given mutex. If the mutex has already been acquired, the call returns immediately with APR_EBUSY. Note: it is important that the APR_STATUS_IS_EBUSY(s) macro be used to determine if the return value was APR_EBUSY, for portability reasons.

  $ret = $mutex->trylock();

obj: $mutex ( APR::ThreadMutex object (docs::2.0::api::APR::ThreadMutex) )

the mutex on which to attempt the lock acquiring.

ret: $ret (integer)

since: subject to change

META: Autogenerated - needs to be reviewed/completed

Release the lock for the given mutex.

  $ret = $mutex->unlock();

obj: $mutex ( APR::ThreadMutex object (docs::2.0::api::APR::ThreadMutex) )

the mutex from which to release the lock.

ret: $ret ( integer )

since: subject to change
