Thread::RWLock 1.02

RWLocks provide a mechanism to regulate access to resources. Multiple concurrent reader may hold the rwlock at the same time, while a writer holds the lock exclusively.<br /><br />New reader threads are blocked if any writer are currently waiting to obtain the lock. The read lock gets through after all write lock requests have completed.<br /><br />Thread::RWLock also takes into account that one thread may obtain multiple readlocks at the same time and prevents deadlocking in this case.<br /><br />SYNOPSIS<br /><br /> use Thread::RWLock;<br /><br /> my $rwlock = new Thread::RWLock;<br /><br /> # Reader<br /> $rwlock->down_read;<br /> $rwlock->up_read;<br /><br /> # Writer<br /> $rwlock->down_write;<br /> $rwlock->up_write;
