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.
