SYNOPSIS

       #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_setkind_np() returns 0 on success and a non-zero error code on error.

ERRORS

       On error, pthread_mutexattr_setkind_np() returns the following error code:

       EINVAL kind     is     neither     PTHREAD_MUTEX_FAST_NP     nor      PTHREAD_MUTEX_RECURSIVE_NP      nor
              PTHREAD_MUTEX_ERRORCHECK_NP.
