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

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