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
