pthread_mutexattr_setprioceiling()
Set the priority ceiling of a mutex attribute object
Synopsis:
#include <pthread.h>
int pthread_mutexattr_setprioceiling(
pthread_mutexattr_t* attr,
int prioceiling );
Since:
BlackBerry 10.0.0
Arguments:
- attr
- A pointer to the pthread_mutexattr_t object that you want to set the attribute in.

Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
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().
In order to change the priority ceiling to a value above the maximum permitted for unprivileged processes, your process must have the PROCMGR_AID_PRIORITY ability enabled. For more information, see procmgr_ability().
Returns:
- EOK
- Success.
- EINVAL
- Invalid value specified by attr or prioceiling.
- EPERM
- The calling process doesn't have the required permission; see procmgr_ability().
