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.

The pthread_hello project builds one executable: p_hello.

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_hello

./p_hello n

where n is number of threads

Usage Example

root@PPCE7:/tmp# ./p_hello 3
Hello from node 0
Hello from node 2
Hello from node 1

Summary

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