 * Test that clock_getres() sets errno=EINVAL for a variety of
 * invalid clock_ids.
 *
 * The following invalid clock_ids will be used:
 * - Boundary values for integers (TBD if clock_id is an integer)
 *   MIN INT = INT32_MIN
 *   MAX INT = INT32_MAX
 *   MIN INT - 1 = 2147483647  (this is what gcc will set to)
 *   MAX INT + 1 = -2147483647 (this is what gcc will set to)
 *   unassigned value = -1073743192 (ex. of what gcc will set to)
 *   unassigned value = 1073743192 (ex. of what gcc will set to)
 *   -1
 *   17 (currently not = to any clock)
