+.Sh DESCRIPTION
+Thread attributes are used to specify parameters to
+.Fn pthread_create .
+One attribute object can be used in multiple calls to
+.Fn pthread_create ,
+with or without modifications between calls.
+.Pp
+The
+.Fn pthread_attr_init
+function initializes
+.Fa attr
+with all the default thread attributes.
+.Pp
+The
+.Fn pthread_attr_destroy
+function destroys
+.Fa attr .
+.Pp
+The
+.Fn pthread_attr_set*
+functions set the attribute that corresponds to each function name.
+.Pp
+The
+.Fn pthread_attr_get*
+functions copy the value of the attribute that corresponds to each function name
+to the location pointed to by the second function parameter.
+.Sh RETURN VALUES
+If successful, these functions return 0.
+Otherwise, an error number is returned to indicate the error.
