16 /* The size of memory buffers to display on failure */
17 #define MEM_BUFFER_SIZE (21)
20 * A common routine to output test failure messages. Generally this should not
21 * be called directly, rather it should be called by the following functions.
23 * |desc| is a printf formatted description with arguments |args| that is
24 * supplied by the user and |desc| can be NULL. |type| is the data type
25 * that was tested (int, char, ptr, ...). |fmt| is a system provided
26 * printf format with following arguments that spell out the failure
27 * details i.e. the actual values compared and the operator used.
29 * The typical use for this is from an utility test function:
31 * int test6(const char *file, int line, int n) {
33 * test_fail_message(1, file, line, "int", "value %d is not %d", n, 6);
39 * calling test6(3, "oops") will return 0 and produce out along the lines of:
40 * FAIL oops: (int) value 3 is not 6\n
42 * It general, test_fail_message should not be called directly.

124 * Define some comparisons between pairs of various types.
125 * These functions return 1 if the test is true.
126 * Otherwise, they return 0 and pretty-print diagnostics.
128 * In each case the functions produced are:
129 * int test_name_eq(const type t1, const type t2, const char *desc, ...);
130 * int test_name_ne(const type t1, const type t2, const char *desc, ...);
131 * int test_name_lt(const type t1, const type t2, const char *desc, ...);
132 * int test_name_le(const type t1, const type t2, const char *desc, ...);
133 * int test_name_gt(const type t1, const type t2, const char *desc, ...);
134 * int test_name_ge(const type t1, const type t2, const char *desc, ...);
136 * The t1 and t2 arguments are to be compared for equality, inequality,
137 * less than, less than or equal to, greater than and greater than or
138 * equal to respectively. If the specified condition holds, the functions
139 * return 1. If the condition does not hold, the functions print a diagnostic
140 * message and return 0.
142 * The desc argument is a printf format string followed by its arguments and
143 * this is included in the output if the condition being tested for is false.
