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

|
|
*
|
|
* |desc| is a printf formatted description with arguments |args| that is
|
|
* supplied by the user and |desc| can be NULL. |type| is the data type
|
|
* that was tested (int, char, ptr, ...). |fmt| is a system provided
|
|
* printf format with following arguments that spell out the failure
|
|
* details i.e. the actual values compared and the operator used.
|
|
*
|
|
* The typical use for this is from an utility test function:
|
|
*
|
|
* int test6(const char *file, int line, int n) {
|
|
* if (n != 6) {

* }

* return 1;
|

* }
|
|
*
|
|
* calling test6(3, "oops") will return 0 and produce out along the lines of:
|
|
* FAIL oops: (int) value 3 is not 6\n
