The TapeClassCompareMemory routine compares two memory buffers and returns the number of bytes that are equivalent.
Syntax
SCSIPORT_API ULONG TapeClassCompareMemory(
[in, out] PVOID Source1,
[in, out] PVOID Source2,
[in] ULONG Length
);
Parameters
[in, out] Source1
Pointer to the first buffer to be compared.
