This document describes the CrossWorks Tasking Library (CTL). The tasking (aka multitasking) library provides a multi-priority, preemptive, task switching and synchronization facility. Additionally, it supports a timer, interrupt service routines, and memory-block allocation.

This document is divided into three parts:

• A whistle-stop tour of the tasking library introduces the key concepts.
• Putting the tasking library to use looks in-depth at the tasking library and how to use it in your applications.
• Reference information is a concise reference for each function provided in the tasking library.
