Subj : Re: SGI: Need Something like 1 Mutual Exclusion Semaphore for Multible Programs To : comp.programming,comp.sys.sgi.misc From : clusardi2k Date : Thu Jul 07 2005 08:08 am I'm going to find on the Internet a program that does the sequence: sem_open sem_init sem_wait sem_post sem_post The only thing I have to find out is how how do I declare the semaphore to be in shared memory.
