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.

2. Open the fbench project files.

3. Build the fbench project.

4. Upload the fbench and ffbench executables to the target system.

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_hello

./p_hello n

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