|
Cothreads are a simple user-space method for switching between
|
|
subtasks. They're based on setjmp()/longjmp() in their current form.

</para>

<para>
|
|
Cothreads are used for loop-based elements that pull data instead
|
|
of being fed with data. They can also be used to pull a specific region
|
|
of data out of their src element.
