Example pthread demo

TODO: {{#todo:Review(12.11.13-12:03->JG+);(12.11.13-17:25->MD-)|Jgreene|oe 4,oe 5,jg,md,Buggy}}

This is a guide to the pthread_demo 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 pthread_demo project builds one executable: p_thread_demo.

Opening, Building and Uploading the Project Files

1. Open the C/C++ editing perspective.

Usage and Behavior

This page needs information regarding the pthread code, to point to the parts that are of interest for writing multithreaded code using pthreads.

Hardware Requirements

The pthread_demo C example project has no special hardware requirements. It should run just fine on any system for which the project files 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 C example project demonstrates how to use pthreads. For another example of pthread usage see Example pthread hello.
