NAME

       Coro::Specific - manage coroutine-specific variables.

SYNOPSIS

	use Coro::Specific;

	my $ref = new Coro::Specific;

	$$ref = 5;
	print $$ref;

DESCRIPTION

       This module can be used to create variables (or better: references to them) that are specific to the currently executing coroutine. This
       module does not automatically load the Coro module (so the overhead will be small when no coroutines are used).

       A much faster method is to store extra keys into %$Coro::current - all you have to do is to make sure that the key is unique (e.g. by
       prefixing it with your module name). You can even store data there before loading the Coro module - when Coro is loaded, the keys stored in
       %$Coro::current are automatically attached to the coro thread executing the main program.

       You don't have to load "Coro::Specific" manually, it will be loaded automatically when you "use Coro" and call the "new" constructor.

       new Create a new coroutine-specific scalar and return a reference to it. The scalar is guarenteed to be "undef". Once such a scalar has
	   been allocated you cannot deallocate it (yet), so allocate only when you must.

BUGS

       The actual coroutine specific values do not automatically get destroyed when the Coro::Specific object gets destroyed.

Storable(3pm)						User Contributed Perl Documentation					     Storable(3pm)

NAME

       Coro::Storable - offer a more fine-grained Storable interface

SYNOPSIS

	use Coro::Storable;

DESCRIPTION

       This module implements a few functions from the Storable module in a way so that it cede's more often. Some applications (such as the
       Deliantra game server) sometimes need to load large Storable objects without blocking the server for a long time.

       This is being implemented by using a perlio layer that feeds only small amounts of data (4096 bytes per call) into Storable, and
       "Coro::cede"'ing regularly (at most 100 times per second by default, though).

       As Storable is not reentrant, this module also wraps most functions of the Storable module so that only one freeze or thaw is done at any
       one moment (and recursive invocations are not currently supported).

FUNCTIONS

       $ref = thaw $pst
	   Retrieve an object from the given $pst, which must have been created with "Coro::Storable::freeze" or
	   "Storable::store_fd"/"Storable::store" (sorry, but Storable uses incompatible formats for disk/mem objects).

	   This function will cede regularly.

       $pst = freeze $ref
	   Freeze the given scalar into a Storable object. It uses the same format as "Storable::store_fd".

	   This functino will cede regularly.

       $pst = nfreeze $ref
	   Same as "freeze" but is compatible to "Storable::nstore_fd" (note the "n").

       $pst = blocking_freeze $ref
	   Same as "freeze" but is guaranteed to block. This is useful e.g. in "Coro::Util::fork_eval" when you want to serialise a data structure
	   for use with the "thaw" function for this module. You cannot use "Storable::freeze" for this as Storable uses incompatible formats for
	   memory and file images, and this module uses file images.

       $pst = blocking_nfreeze $ref
	   Same as "blocking_freeze" but uses "nfreeze" internally.

       $guard = guard
	   Acquire the Storable lock, for when you want to call Storable yourself.

	   Note that this module already wraps all Storable functions, so there is rarely the need to do this yourself.
