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.

NAME

       pthread_mutexattr_setkind_np, pthread_mutexattr_getkind_np - deprecated mutex creation attributes

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);

DESCRIPTION

       These functions are deprecated, use pthread_mutexattr_settype(3) and pthread_mutexattr_gettype(3) instead.

RETURN VALUE

       pthread_mutexattr_getkind_np always returns 0.

       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
