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 = 693451072
generating new random data
reader: count = 1, data = 1195545710
generating new random data
reader: count = 2, data = 462104121
Summary
The pthread demo is an example of C programming and demonstrates how to use pthreads.
