NAME

APR::ThreadMutex - Perl API for APR thread mutexes

Synopsis

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

Description

"APR::ThreadMutex" interfaces APR thread mutexes.

API

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

Unsupported API

"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 so we can help each other take the steps necessary to shift the method to an officially supported API.

"DESTROY"

META: Autogenerated - needs to be reviewed/completed

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

  $mutex->DESTROY();
the mutex to destroy.

"lock"

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();
the mutex on which to acquire the lock.

"new"

Create a new mutex

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

"pool_get"

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();
apr_pool_t the pool

"trylock"

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();
the mutex on which to attempt the lock acquiring.

"unlock"

META: Autogenerated - needs to be reviewed/completed

Release the lock for the given mutex.

  $ret = $mutex->unlock();
the mutex from which to release the lock.
