NAME
APR::ThreadRWLock - Perl API for APR thread read/write locks
Synopsis
use APR::ThreadRWLock ();
my $mutex = APR::ThreadRWLock->new($r->pool);
$mutex->rdlock;
$mutex->wrlock;
$mutex->tryrdlock;
$mutex->trywrlock;
$mutex->unlock;
Description
"APR::ThreadRWLock" interfaces APR thread read/write locks.
See srclib/apr/locks/unix/thread_rwlock.c in your Apache source tree. At the time of this writing these methods are not supported on all
platforms. Thus, check your libraries!
API
"APR::ThreadRWLock" provides the following functions and/or methods:
Unsupported API
"APR::ThreadRWLock" 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 lock and free the associated memory.
$lock->DESTROY();
obj: $lock ( "APR::ThreadRWLock object" )
the lock to destroy.
ret: no return value
since: subject to change
"rdlock"
META: Autogenerated - needs to be reviewed/completed
Acquire the read lock for the given lock. The calling thread acquires the read lock if a writer does not hold the lock and there are no
writers blocked on the lock. Otherwize it is put to sleep until these conditions are met.
$ret = $lock->rdlock();
obj: $lock ( "APR::ThreadRWLock object" )
the lock on which to acquire the lock.
ret: $ret ( integer )
since: subject to change
"tryrdlock"
META: Autogenerated - needs to be reviewed/completed
Performs the same operation as "rdlock" with the exception that the function shall fail if the thread would be blocked.
$ret = $lock->tryrdlock();
obj: $lock ( "APR::ThreadRWLock object" )
the lock on which to acquire the lock.
ret: $ret ( integer )
since: subject to change
"wrlock"
META: Autogenerated - needs to be reviewed/completed
Acquire the write lock for the given lock. The calling thread acquires the write lock if if no other thread (reader or writer) holds it.
Otherwize it is put to sleep until this condition is met.
$ret = $lock->wrlock();
obj: $lock ( "APR::ThreadRWLock object" )
the lock on which to acquire the lock.
ret: $ret ( integer )
since: subject to change
"trywrlock"
META: Autogenerated - needs to be reviewed/completed

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_lock.
$ret = $obj->pool_get();
obj: $obj ( "APR::ThreadRWLock object" )
ret: $ret ( "APR::Pool object" )
