NAME

       Thread::Pool::Simple - A simple thread-pool implementation

SYNOPSIS

	 use Thread::Pool::Simple;

	 my $pool = Thread::Pool::Simple->new(
			min => 3,	    # at least 3 workers
			max => 5,	    # at most 5 workers
			load => 10,	    # increase worker if on average every worker has 10 jobs waiting
			init => [&init_handle, $arg1, $arg2, ...]   # run before creating worker thread
			pre => [&pre_handle, $arg1, $arg2, ...]   # run after creating worker thread
			do => [&do_handle, $arg1, $arg2, ...]	   # job handler for each worker
			post => [&post_handle, $arg1, $arg2, ...] # run before worker threads end
			passid => 1,	    # whether to pass the job id as the first argument to the &do_handle
			lifespan => 10000,  # total jobs handled by each worker
		      );

	 my ($id1) = $pool->add(@arg1); # call in list context
	 my $id2 = $pool->add(@arg2);	# call in scalar conetxt
	 $pool->add(@arg3)		# call in void context

	 my @ret = $pool->remove($id1); # get result (block)
	 my $ret = $pool->remove_nb($id2); # get result (no block)

	 $pool->cancel($id1);		# cancel the job
	 $pool->cancel_all();		# cancel all jobs

	 $pool->join(); 		# wait till all jobs are done
	 $pool->detach();		# don't wait.

DESCRIPTION

       "Thread::Pool::Simple" provides a simple thread-pool implementaion without external dependencies outside core modules.

       Jobs can be submitted to and handled by multi-threaded `workers' managed by the pool.

NAME

       APR::BucketAlloc - Perl API for Bucket Allocation

Synopsis
	 use APR::BucketAlloc ();
	 $ba = APR::BucketAlloc->new($pool);
	 $ba->destroy;

Description
       "APR::BucketAlloc" is used for bucket allocation.

   "new"
       Create an "APR::BucketAlloc" object:

	 $ba = APR::BucketAlloc->new($pool);

       class: "APR::BucketAlloc"
       arg1: $pool ( "APR::Pool object" )
	   The pool used to create this object.

       ret: $ba ( "APR::BucketAlloc object" )
	   The new object.

       since: 2.0.00

       This bucket allocation list (freelist) is used to create new buckets (via "APR::Bucket->new") and bucket brigades (via
       "APR::Brigade->new").

       You only need to use this method if you aren't running under httpd.  If you are running under mod_perl, you already have a bucket
       allocation available via "$c->bucket_alloc" and "$bb->bucket_alloc".

       Example:

	 use APR::BucketAlloc ();
	 use APR::Pool ();
	 my $ba = APR::BucketAlloc->(APR::Pool->pool);
	 my $eos_b = APR::Bucket::eos_create($ba);

   "destroy"
       Destroy an "APR::BucketAlloc object":

	 $ba->destroy;

       arg1: $ba ( "APR::BucketAlloc object" )
	   The freelist to destroy.

       ret: no return value
       since: 2.0.00

       Once destroyed this object may not be used again.

       You need to destroy $ba only if you have created it via "APR::BucketAlloc->new". If you try to destroy an allocation not created by this
       method, you will get a segmentation fault.

       Moreover normally it is not necessary to destroy allocators, since the pool which created them will destroy them during that pool's cleanup
       phase.
