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();

obj: $mutex ( "APR::ThreadMutex object" )
    the mutex to destroy.

ret: no return value
since: subject to change

  "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();

obj: $mutex ( "APR::ThreadMutex object" )
    the mutex on which to acquire the lock.

ret: $ret ( integer )
since: subject to change

  "new"
Create a new mutex

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

obj: "APR::ThreadMutex" ( class name )
arg1: $p ( "APR::Pool object" )
ret: $mutex ( "APR::ThreadMutex object" )
since: subject to change

  "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();

obj: $obj ( "APR::ThreadMutex object" )
ret: $ret ( "APR::Pool object" )
    apr_pool_t the pool

since: subject to change

  "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();

obj: $mutex ( "APR::ThreadMutex object" )
    the mutex on which to attempt the lock acquiring.

ret: $ret (integer)
since: subject to change

  "unlock"
META: Autogenerated - needs to be reviewed/completed

Release the lock for the given mutex.

  $ret = $mutex->unlock();

obj: $mutex ( "APR::ThreadMutex object" )
    the mutex from which to release the lock.

ret: $ret ( integer )
since: subject to change
