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
