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.

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.
