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