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
