TODO: {{#todo:InProgress(11.14.13-15:47->JG+)|Jgreene|oe 4,oe 5,jg,md,InProgress}}

This is a guide to the pthread C example project included in the EMAC OE SDK.

This is a simple pthreads example application. A single thread is created to generate random data that is read by a specified number of reader threads.

The term Pthread refers to POSIX Threads, a POSIX standard for threads. The standard: POSIX.1c, Threads extensions, defines an API for creating and manipulating threads.

Usage and Behavior

Hardware Requirements

The pthread demo has no special hardware requirements. It should run just fine on any system for which the pthread demo project code can be successfully compiled.

Using pthread_demo

./pthread_demo n

where n is the number of threads

Usage Example

root@PPCE7:/tmp# ./pthread_demo 3
generating new random data
generating new random data
    reader: count = 0, data = 693451072
generating new random data
    reader: count = 1, data = 1195545710
generating new random data
    reader: count = 2, data = 462104121

Summary

The pthread demo is an example of C programming and demonstrates how to use pthreads.
