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
