Get the priority ceiling of a mutex attribute object
#include <pthread.h> int pthread_mutexattr_getprioceiling( const pthread_mutexattr_t* attr, int* prioceiling );
- A pointer to the pthread_mutexattr_t object that you want to get the attribute from.
- A pointer to a location where the function can store the priority ceiling.
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().
- Invalid value specified by attr or prioceiling.
- The caller doesn't have the privilege to perform the operation.
