+  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 16-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 16-bit boundary, then ASSERT().
+  If Length is not aligned on a 16-bit boundary, then ASSERT().
+  If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().

+  @param  Buffer      The pointer to the target buffer to scan.
