29.Os
30.Sh NAME
31.Nm pthread_mutexattr_getkind_np ,
32.Nm pthread_mutexattr_setkind_np
33.Nd mutex attribute operations (legacy)
34.Sh LIBRARY
35.Lb libpthread
36.Sh SYNOPSIS
37.In pthread_np.h
38.Ft int
39.Fn pthread_mutexattr_getkind_np "pthread_mutexattr_t attr"
40.Ft int
41.Fn pthread_mutexattr_setkind_np "pthread_mutexattr_t *attr" "int kind"
42.Sh DESCRIPTION
43.Bf -symbolic
44These functions are deprecated and non-portable implementation of
45the mutex type manipulation.
46.Ef
47.Pp
48It is recommended to use the
49.Xr pthread_mutexattr_gettype 3
50and
51.Xr pthread_mutexattr_settype 3
52functions instead.
53.Sh RETURN VALUES
54The
55.Fn pthread_mutexattr_getkind_np
56function returns a positive value representing the
57.Dq kind
58of the mutex attribute
59.Fa attr
60if successful; otherwise the value \-1 is returned and the global variable
61.Va errno
62is set to indicate the error.
63.Pp
64.Rv -std pthread_mutexattr_setkind_np
65.Sh ERRORS
66The
67.Fn pthread_mutexattr_getkind_np
68and
69.Fn pthread_mutexattr_setkind_np
70functions will fail if:
71.Bl -tag -width Er
72.It Bq Er EINVAL
73The value specified by
74.Fa attr
75is invalid.
