Get the priority ceiling of a mutex attribute object

Synopsis:

#include <pthread.h>

int pthread_mutexattr_getprioceiling( 
            const pthread_mutexattr_t* attr, 
            int* prioceiling );

Arguments:

attr

A pointer to the pthread_mutexattr_t object that you want to get the attribute from.

prioceiling

A pointer to a location where the function can store the priority ceiling.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.
