46  * A common routine to output test failure messages.  Generally this should not
47  * be called directly, rather it should be called by the following functions.
48  *
49  * |desc| is a printf formatted description with arguments |args| that is
50  * supplied by the user and |desc| can be NULL.  |type| is the data type
51  * that was tested (int, char, ptr, ...).  |fmt| is a system provided
52  * printf format with following arguments that spell out the failure
53  * details i.e. the actual values compared and the operator used.
54  *
55  * The typical use for this is from an utility test function:
56  *
57  * int test6(const char *file, int line, int n) {
58  *     if (n != 6) {
59  *         test_fail_message(1, file, line, "int", "value %d is not %d", n, 6);
60  *         return 0;
61  *     }
62  *     return 1;
63  * }
64  *
65  * calling test6(3, "oops") will return 0 and produce out along the lines of:
66  *      FAIL oops: (int) value 3 is not 6\n
