Function Documentation

mcuxClMemory_clear()

void mcuxClMemory_clear	(	uint8_t *	pDst,
		size_t	length,
		size_t	bufLength )

Overwrites a memory buffer with null bytes.

If the destination buffer is too small, i.e. if bufLength < length, (length-bufLength) is added to the Flow Protection token (see Flow Protection API).

Parameters

[out]	pDst	Pointer to the buffer to be cleared.
[in]	length	size (in bytes) to be cleared.
[in]	bufLength	buffer size (if bufLength < length, only bufLength bytes are cleared).
