Interfaces documented on this reference page conform to industry standards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
Mutex attributes object whose mutex type attribute is to be modified. New value for the mutex type attribute. The type argument specifies the type of mutex that will be created. Valid values are: PTHREAD_MUTEX_NORMAL PTHREAD_MUTEX_DEFAULT (default) PTHREAD_MUTEX_RECURSIVE PTHREAD_MUTEX_ERRORCHECK
This routine sets the mutex type attribute that is used to determine which type of mutex is created based on a subsequent call to pthread_mutex_init(3).
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. The value specified for attr or type is invalid. The value specified by attr does not refer to an existing mutex attributes object.
Functions: pthread_mutexattr_init(3), pthread_mutexattr_gettype(3), pthread_mutex_init(3)
