Function Documentation

count_fields()

int count_fields	(	char *	line,
		int	delim
	)

Returns the number of delim separated fields occur in line.

error_string()

char * error_string

(

mp_result

res

)

Returns a static label string describing res.

Note that this is not the same as the error string returned by mp_error_string, but corresponds to the spelling of the constant for its value.

find_test()

int find_test	(	char *	code,
		test_t *	info
	)

Locates the run instructions for the specified test code, and if they are found populates *info with a copy.

It returns -1 if code is unknown.

is_blank()

process_file()

bool process_file	(	char *	file_name,
		FILE *	ifp,
		FILE *	ofp
	)

Reads and runs test cases from ifp and writes test results to ofp.

The given file_name is used for cosmetic attribution. The return value is true if all tests passed, false if any tests failed or had errors.

run_test()

int run_test	(	int	test_num,
		testspec_t *	t,
		FILE *	ofp
	)

Runs the test cases specified by t, and writes its results to ofp.

The test_num is used in log output and should reflect the global ordering of tests, but is not otherwise interpreted by this function.

This function returns 0 if the test succeeds, 1 if the test fails, and -1 if the test is broken (e.g., its code is unknown).
