AVIBuildFilter  15EAQWK 

The AVIBuildFilter function builds a filter specification that is subsequently used by the GetOpenFileNameFZGRJG or GetSaveFileName182.5BE function.

STDAPI AVIBuildFilter(

    LPTSTR lpszFilter,

 

    LONG cbFilter,

 

    BOOL fSaving

 

   );

 

 

Parameters

lpszFilter

Address of the buffer containing the filter string.

cbFilter

Size, in bytes, of buffer pointed to by lpszFilter.

fSaving

Flag that indicates whether the filter should include read or write formats. Specify TRUE to include write formats or FALSE to include read formats.

 

Return Values

Returns AVIERR_OK if successful or an error otherwise. Possible error values include the following:

AVIERR_BUFFERTOOSMALL

The buffer size cbFilter was smaller than the generated filter specification.
