-.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.
