StringFromGUID2

Converts a globally unique identifier (GUID) into a string of printable characters.

StringFromGUID2(

REFGUID rguid,

//Interface identifier to be converted

LPOLESTR lpsz,

//Pointer to the resulting string on return

int cbMax

//Maximum size the returned string is expected to be

);

Parameters

rguid: [in] Interface identifier to be converted.
lpsz: [out] Pointer to the resulting string on return.
cbMax: [in] Maximum size the returned string is expected to be.

Return Values

0 (zero): Buffer is too small for returned string.
Non-zero value: The number of characters in the returned string, including the null terminator.

Remarks

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.
