Mocking can still be done with #define, but the --wrap feature of the linker 
is much more elegant.


char *mock_strdup(const char *p);

#define strdup mock_strdup

char *test_strdup(const char *p)
	static int count = 0;
	char *x;
	size_t len;

	if (count % 10 == 0) {
		errno = EINVAL;
		return NULL;

	x = calloc(1, len + 1);
	if (x == NULL) {
		return NULL;
	memcpy(x, p, len);

	return x;


I think we need an example in the code for this.
