Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_mutexattr_getprioceiling() function sets prioceiling to the current mutex attribute attr's scheduling priority ceiling. The mutex attribute object attr must have been previously created with pthread_mutexattr_init().
