TapeClassCompareMemory compares two memory buffers and returns the number of bytes that are equivalent.
TapeClassCompareMemory returns the number of bytes that are equivalent.
A tape miniclass driver uses TapeClassCompareMemory to compare memory in a portable way. For example, a miniclass driver uses TapeClassCompareMemory in its TapeMiniVerifyInquiry routine to determine whether a given product ID matches one of the devices the driver supports.
