.. _String_Compare:

===================================
String_Compare 
===================================

A case *sensitive* string comparison that compares two zero terminated strings for a difference.
    
::

   String_Compare PROTO lpszString1:QWORD, lpszString2:QWORD


**Parameters**

* ``lpszString1`` - The address of the first zero terminated string to compare.
* ``lpszString2`` - The address of the second zero terminated string to compare.


**Returns**

If the two strings match, the return value is the length of the string. 
If there is no match, the return value is ``0``.

**Notes**

The function can be used on strings that may be of uneven length as the terminator will produce the mismatch even if the rest of the characters match.

**Example**

::

   Invoke String_Compare
