+.Sh NAME
+.Nm pthread_mutexattr_getkind_np ,
+.Nm pthread_mutexattr_setkind_np
+.Nd mutex attribute operations (LEGACY)
+.Sh LIBRARY
+.Lb libc_r
+.Sh SYNOPSIS
+.In pthread_np.h
+.Ft int
+.Fn pthread_mutexattr_getkind_np "pthread_mutexattr_t attr"
+.Ft int
+.Fn pthread_mutexattr_setkind_np "pthread_mutexattr_t *attr" "int kind"
+.Sh DESCRIPTION
+These functions are DEPRECATED and NON-PORTABLE implementation of mutex types
+manipulation.
+.Pp
+It's recomended to use
+.Fn pthread_mutexattr_gettype
+and
+.Fn pthread_mutexattr_settype
+functions instead.
+.Sh RETURN VALUES
+The
+.Fn pthread_mutexattr_getkind_np
+function returns positive value representing
+.Ft kind
+of mutex attribute
+.Fa attr
+if successful; otherwise the value -1 is returned and the global variable
+.Fa errno
+is set to indicate the error.
+.Pp
+The
+.Fn pthread_mutexattr_settype
+function returns the value 0 if successful; otherwise
+the value -1 is returned and the global variable
+.Fa errno
+is set to indicate the error.
+.Sh ERRORS
+The
+.Fn pthread_mutexattr_getkind_np
+and
+.Fn pthread_mutexattr_setkind_np
+functions will fail if:
+.Bl -tag -witdh Er
+.It Bq Er EINVAL
+The value specified by
