# Log::Log4perl::Util::Semaphore - phpMan

## NAME
    [Log::Log4perl::Util::Semaphore] - Easy to use semaphores

## SYNOPSIS
        use [Log::Log4perl::Util::Semaphore];
        my $sem = [Log::Log4perl::Util::Semaphore]->new( key => "abc" );

        $sem->semlock();
          # ... critical section
        $sem->semunlock();

        $sem->semset( uid  => (getpwnam("hugo"))[2],
                      gid  => 102,
                      mode => 0644
                    );

## DESCRIPTION
    [Log::Log4perl::Util::Semaphore] provides the synchronisation mechanism
    for the Synchronized.pm appender in Log4perl, but can be used
    independently of Log4perl.

    As a convenience, the "uid" field accepts user names as well, which it
    translates into the corresponding uid by running "getpwnam".
