Function Documentation

sion_swap()

void sion_swap	(	void *	target,
		void *	source,
		int	size,
		int	n,
		int	do_swap
	)

@ brief Perform byte-order swapping for arrays

n elements of size bytes each are swapped if do_swap is true. In-place swapping (target == source) is allowed. If target != source, the buffers must not overlap.

Parameters

[out]	target	the byte-swapped data is written starting at this address
[in]	source	the data to be byte-swapped is read starting at this address
[in]	size	the size (in bytes) of a single element
[in]	n	the number of elements to be byte-swapped
[in]	do_swap	byte-swapping is only performed if this argument is true
