Check()

BOOL TCRC_32_Base::Check	(	VOID *	void_Data,
		U32	u32_Size,
		U32	u32_Expected_CRC
	)

Check CRC of the data buffer.

Parameters

[in]	*void_Data	- Pointer to the data buffer
[in]	u32_Size	- Size of the data buffer
[in]	u32_Expected_CRC	- Expected CRC of the data buffer

Returns

BOOL - Data buffer CRC checking status

Return values

false	- CRC of the buffer not match to expected CRC
true	- CRC of the buffer match to expected CRC
