Function Documentation

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.
