◆ fc_real_calloc()

void * fc_real_calloc	(	size_t	nelem,
		size_t	elsize,
		const char *	called_as,
		int	line,
		const char *	file
	)

Function used by fc_calloc macro, calloc() replacement No need to check return value.

I'm pretty sure only the product of nelem and elsize can ever matter here, and not their individual values. (As a matter of C.) Except this function doesn't support calloc-ing more memory than can be expressing using a single size_t, but that's not likely to be a problem.

◆ fc_real_malloc()

void * fc_real_malloc	(	size_t	size,
		const char *	called_as,
		int	line,
		const char *	file
	)

Function used by fc_malloc macro, malloc() replacement

There's no need for the caller to check return value; this function will always return a valid pointer (even for a 0-byte malloc).

void * fc_real_realloc	(	void *	ptr,

Function used by fc_realloc macro, realloc() replacement No need to check return value.

static

Do whatever we should do when malloc fails. At the moment this just prints a log message and calls exit(EXIT_FAILURE)

char * real_fc_strdup	(	const char *	str,
