Thread::RWLock

RWLocks provide a mechanism to regulate access to resources. Multiple concurrent readers may hold the rwlock at the same time, while a writer holds the lock exclusively.

use Thread::RWLock;
my $rwlock = new Thread::RWLock;

# In the reader thread
$rwlock->down_read;
# update some shared variables
$rwlock->up_read;

# In the writer thread
$rwlock->down_write;
# use some shared variables
$rwlock->up_write;
