<div class="markdown_content"><p>hI,<br/> We have implemented shared memory in Codesys environment. This application is downloaded on to the QNX based Power PC target. Another QNX application is accessing the same shared memory. We are writing data from Codesys application on to the shared memory and reading the same from the QNX application successfully.<br/> There seems to be no clash in writing and reading from different applications.<br/> But we understand that some synchronization mechanism has to be used to avoid simultaneous access of shared memory.<br/> How can we implement this from the codesys application and achieve the synchronization.?<br/> Can you provide any examples which will help us understand it. What are the libraries to be use in the same?</p> <p>With regards,<br/> praveena</p></div>
