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
