PTHREAD_MUTEXATTR_GETKIND_NP(3) 			   BSD Library Functions Manual 			   PTHREAD_MUTEXATTR_GETKIND_NP(3)

NAME
     pthread_mutexattr_getkind_np, pthread_mutexattr_setkind_np -- mutex attribute operations (legacy)

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread_np.h>

     int
     pthread_mutexattr_getkind_np(pthread_mutexattr_t attr);

     int
     pthread_mutexattr_setkind_np(pthread_mutexattr_t *attr, int kind);

DESCRIPTION
     These functions are deprecated and non-portable implementation of the mutex type manipulation.

     It is recommended to use the pthread_mutexattr_gettype(3) and pthread_mutexattr_settype(3) functions instead.

RETURN VALUES
     The pthread_mutexattr_getkind_np() function returns a positive value representing the ``kind'' of the mutex attribute attr if successful;
     otherwise the value -1 is returned and the global variable errno is set to indicate the error.

     The pthread_mutexattr_setkind_np() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable
     errno is set to indicate the error.

ERRORS
     The pthread_mutexattr_getkind_np() and pthread_mutexattr_setkind_np() functions will fail if:

     [EINVAL]		The value specified by attr is invalid.
