Functions
static int	nxs_memory_asprintf (char **ret, const char *format,...)
	Sets *ret to be a pointer to a buffer, which should be freed, large enough to hold a string formatted with format and any following arguments.
void *	nxs_memory_reallocf (void *ptr, size_t size)
	Identical to the standard library realloc() function, except that ptr will be freed if the allocation fails.
void	nxs_memory_swap (void *restrict ptrA, void *restrict ptrB, size_t size)
	Swaps the first size bytes of the data pointed to by ptrA and the data pointed to by ptrB.
int	nxs_memory_vasprintf (char **ret, const char *format, va_list arg)
	Sets *ret to be a pointer to a buffer, which should be freed, large enough to hold a string formatted with format and the arguments referenced by arg.

Function Documentation

static int nxs_memory_asprintf	(	char **	ret,
		const char *	format,
			...
	)			[inline, static]

Sets *ret to be a pointer to a buffer, which should be freed, large enough to hold a string formatted with format and any following arguments.

If allocation fails, -1 is returned and ret is set to NULL. An error formatting the string will return a negative value and ret may not be set to NULL.

void* nxs_memory_reallocf	(	void *	ptr,
		size_t	size
	)

Identical to the standard library realloc() function, except that ptr will be freed if the allocation fails.

void nxs_memory_swap	(	void *restrict	ptrA,
		void *restrict	ptrB,
		size_t	size
	)

Swaps the first size bytes of the data pointed to by ptrA and the data pointed to by ptrB.

This function uses fast, portable, and C99-conformant block copying code based on the natural word size of the runtime architecture.

int nxs_memory_vasprintf	(	char **	ret,
		const char *	format,
		va_list	arg
	)

Sets *ret to be a pointer to a buffer, which should be freed, large enough to hold a string formatted with format and the arguments referenced by arg.

If allocation fails, -1 is returned and ret is set to NULL. An error formatting the string will return a negative value and ret may not be set to NULL.
