If the data has the REG\_SZ, REG\_MULTI\_SZ or REG\_EXPAND\_SZ type, the  
string  
may not have been stored with the proper null-terminating characters.  
For example, if the string data is 12 characters and the buffer is  
larger than that, the function will add the null character and the size  
of the data returned is 13_sizeof(TCHAR) bytes. However, if the buffer  
is 12_sizeof(TCHAR) bytes, the data is stored successfully but does not  
include a terminating null.
