Function Documentation

ScanMem64()

VOID *EFIAPI ScanMem64	(	IN CONST VOID *	Buffer,
		IN UINTN	Length,
		IN UINT64	Value
	)

Scans a target buffer for a 64-bit value, and returns a pointer to the matching 64-bit value in the target buffer.

This function searches the target buffer specified by Buffer and Length from the lowest address to the highest address for a 64-bit value that matches Value. If a match is found, then a pointer to the matching byte in the target buffer is returned. If no match is found, then NULL is returned. If Length is 0, then NULL is returned.

If Length > 0 and Buffer is NULL, then ASSERT(). If Buffer is not aligned on a 64-bit boundary, then ASSERT(). If Length is not aligned on a 64-bit boundary, then ASSERT(). If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().

Parameters

Buffer	The pointer to the target buffer to scan.
Length	The number of bytes in Buffer to scan.
Value	The value to search for in the target buffer.

Returns

A pointer to the matching byte in the target buffer or NULL otherwise.
