In the rare case the client receiving the returned string does not free memory in the string, you might have to free it yourself by using ::SysFreeString.

 SysFreeString Parameters
bstr 
Unicode string that was allocated previously, or NULL. <code>If NULL, the function simply returns</code>. 
Return Values
None.

Remarks
Passing into this function any invalid and, under some circumstances, <code>NULL pointers will result in unexpected termination of the application.</code>
