47 * A common routine to output test failure messages. Generally this should not

50 * |desc| is a printf formatted description with arguments |args| that is
51 * supplied by the user and |desc| can be NULL. |type| is the data type
52 * that was tested (int, char, ptr, ...). |fmt| is a system provided
53 * printf format with following arguments that spell out the failure
54 * details i.e. the actual values compared and the operator used.
