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.

INTRO what is a pthread?

Opening, Building and Uploading the Project Files

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

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 = 677351334

    reader: count = 1, data = 317767096
generating new random data
    reader: count = 2, data = 522450509
