NAME

Coro - coroutine process abstraction

SYNOPSIS

 use Coro;

 async {
    # some asynchronous thread of execution
 };

 # alternatively create an async process like this:

 sub some_func : Coro {
    # some more async code
 }

 yield;

DESCRIPTION

$main

This coroutine represents the main program.

$current

The current coroutine (the last coroutine switched to). The initial value is $main (of course).

$idle

The coroutine to switch to when no other coroutine is running. The default implementation prints "FATAL: deadlock detected" and exits.

STATIC METHODS

Static methods are actually functions that operate on the current process only.

async { ... };

Create a new asynchronous process and return it's process object (usually unused). When the sub returns the new process is automatically terminated.

schedule

Calls the scheduler. Please note that the current process will not be put into the ready queue, so calling this function usually means you will never be called again.

yield

Yield to other processes. This function puts the current process into the ready queue and calls schedule.

terminate

Terminates the current process.

# dynamic methods

PROCESS METHODS

These are the methods you can call on process objects.

new Coro \⊂

Create a new process and return it. When the sub returns the process automatically terminates. To start the process you must first put it into the ready queue by calling the ready method.

$process->ready

Put the current process into the ready queue.

SEE ALSO

Coro::Channel, Coro::Cont, Coro::Specific, Coro::Semaphore, Coro::Signal, Coro::State, Coro::Event.
