Set the priority ceiling of a mutex attribute object
#include <pthread.h> int pthread_mutexattr_setprioceiling( pthread_mutexattr_t* attr, int prioceiling );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_mutexattr_setprioceiling() function sets the mutex attribute attr's scheduling priority ceiling to prioceiling. Note that attr must have been previously created with pthread_mutexattr_init().
