Example pthread hello

TODO: {{#todo:InProgress(12.11.13-12:03->JG+)|Jgreene|oe 4,oe 5,jg,md,InProgress}}

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

This is a simple pthreads example application. A number of pthread nodes are created and each reports its existence by printing a hello message to the console.

The term pthread refers to POSIX Threads, a POSIX standard for threads.

Opening, Building and Uploading the Project Files

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

Usage and Behavior

Hardware Requirements

The pthread hello 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

    reader: count = 2, data = 462104121

Summary

The pthread hello C example project demonstrates how to use pthreads. For another example of pthread usage see example pthread demo.
