It provides a single, absolute owner for the section of code (thus a <BR /><BR />critical section) that it brackets between the calls to pthread_mutex_lock()and <BR /><BR />pthread_mutex_unlock(). The first thr ead that locks the mutex getsownership, and any subsequent attempts to lock it will fail, causing the calling <BR /><BR />thread to go to sleep.<BR /><BR /><BR />Maybe it will-maybe not,<BR />Rita Tue, 15 Jan 2002 00:54:07 GMT Rita C Workman 2002-01-15T00:54:07Z https://community.hpe.com/t5/operating-system-hp-ux/pthread-error/m-p/2644617#M879139 anyone seen this error before?<BR /><BR />pthread_setschedparam failed, OS says: not owner^M<BR /><BR />This happens when I run an executable that I compiled. The source is Ada 95 code. The permisions are 777. I am the owner of the file.<BR /><BR />MB Mon, 14 Jan 2002 19:52:42 GMT https://community.hpe.com/t5/operating-system-hp-ux/pthread-error/m-p/2644617#M879139 Mike Burk 2002-01-14T19:52:42Z https://community.hpe.com/t5/operating-system-hp-ux/pthread-error/m-p/2644618#M879140 Did a little reading and the one thing I noticed (may not be what you need..but..) was this:<BR /><BR />Mutexes The mutual exclusion lock is the simplest and most primitive synchr onizationvariable.
