pthread_mutexattr_setkind_np, pthread_mutexattr_getkind_np - deprecated mutex creation attributes
#include <pthread.h>
int pthread_mutexattr_setkind_np(pthread_mutexattr_t *attr, int kind);
int pthread_mutexattr_getkind_np(const pthread_mutexattr_t *attr,
int *kind);These functions are deprecated, use pthread_mutexattr_settype(3) and pthread_mutexattr_gettype(3) instead.
pthread_mutexattr_getkind_np() always returns 0.
pthread_mutexattr_setkind_np() returns 0 on success and a non-zero error code on error.
On error, pthread_mutexattr_setkind_np() returns the following error code:
kind is neither PTHREAD_MUTEX_FAST_NP nor
PTHREAD_MUTEX_RECURSIVE_NP nor
PTHREAD_MUTEX_ERRORCHECK_NP.
