Example pthread demo
This is a guide to the
pthread_demo C example project included in the EMAC OE SDK.
This is a simple pthreads example application. A single thread is created to generate random data that is read by a specified number of reader threads.
pthread_demo project builds one executable:
Opening, Building and Uploading the Project Files
For information on opening the project from within Eclipse, please see Importing the EMAC OE SDK Projects with Eclipse. Then, follow Using the EMAC OE SDK Projects with Eclipse for information on how to build, upload and execute the example.
Makefile can be used with the
make command from the commandline to build and upload the example. For information on this method, please see Using EMAC OE SDK Example Projects.
EMAC SDK 5.X
For information on opening the project from within QtCreator, please see QtCreator: Adding Source Files. Then, follow Getting Started With Qt Creator for information on how to build, upload and execute the example.
CMakefile.txt can be used with the
cmake command from the commandline to build and upload the example. For information on this method, please see Getting Started with the EMAC OE SDK.
Usage and Behavior
pthread_demo project is an example of multithreaded code for generating and interacting with an arbitrary number of pthreads. Within the pthread_demo.c C source file can be found demonstrations of how to, specifically:
- Create pthreads, line 90.
- Write to pthreads, line 141.
- Read from pthreads, line 127.
- Terminate and clean up after pthreads, line 119.
pthread_demo 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.

pthread_demo C example project demonstrates how to use pthreads. For another example of pthread usage see Example pthread hello.
