If the string was declared locally yes it would work, but..
The function only gets the pointer to the string, it has no idea about the 
length of it, all it knows is that it'll have to put the strng it gathers
up in the function into the address provided.  
So sizeof() will return the length of the pointer. 
Perhaps if the string is global it may also work, but i didn't try or even
said that !.:)

PS: if portability is not an issue look at heapwalk in Borland, or go 
2 or 4 bytes (i forget) back from the pointer and you'll find the 
alloced block size somewhere, it only seems to work with the Borland RTL..
