Parameters
rguid
Specifies the interface ID to be converted.

Specifies the maximum size the returned string is expected to be.
Return Values
0 (zero)
Indicates buffer is too small for returned string.
Non-zero value

terminator.
Comments
The string that the lpsz parameter receives has a format like the following sample:
[c200e360-38c5-11ce-ae62-08002b2b79ef]
where the successive fields break the GUID into the form
DWORD-WORD-WORD-WORD-WORD.DWORD covering the 128-bit GUID. The string includes enclosing braces,
which are an OLE convention.
