/**\r
  Scans a target buffer for a 64-bit value, and returns a pointer to the\r
  matching 64-bit value in the target buffer.\r
\r
  This function searches target the buffer specified by Buffer and Length from\r
  the lowest address to the highest address at 64-bit increments for a 64-bit\r
  value that matches Value. If a match is found, then a pointer to the matching\r
  value in the target buffer is returned. If no match is found, then NULL is\r
  returned. If Length is 0, then NULL is returned.\r
\r
  If Buffer is NULL, then ASSERT().\r
  If Buffer is not aligned on a 64-bit boundary, then ASSERT().\r
  If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().\r
\r
  @param  Buffer  Pointer to the target buffer to scan.\r
  @param  Length  Number of bytes in Buffer to scan.\r
  @param  Value   Value to search for in the target buffer.\r
\r
  @return Pointer to the first occurrence or NULL if not found.\r
  @retval NULL  if Length == 0 or Value was not found.\r
