The GetConnectionName method retrieves the connection name specified in the profile.
HRESULT GetConnectionName( WCHAR *pwszName, WORD *pcchName );
Pointer to a wide-character null-terminated string containing the connection name. Pass NULL to retrieve the length required for the name.
On input, a pointer to a variable containing the length of the pwszName array in wide characters (2 bytes). On output, if the method succeeds, the variable contains the length of the name, including the terminating null character.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
||The method succeeded.|
||The pcchName parameter is NULL.|
||The pwszName parameter is not large enough.|
You should make two calls to GetConnectionName. On the first call, pass NULL as pwszName. On return, the value pointed to by pcchName is set to the number of wide characters, including the terminating null, required to hold the connection name. Then you can allocate the required amount of memory for the string and pass a pointer to it as pwszName on the second call.
The connection name is the same as the input name specified on one (or more) of the streams in the profile, so it can be used to match writer inputs to profile streams.
