The GetMediaTypes method retrieves a list of the types of messages that this tool supports.
Syntax
HRESULT GetMediaTypes(
DWORD** padwMediaTypes,
DWORD dwNumElements
);
Parameters
padwMediaTypes
Address of an array of DWORDs. The method fills this array with the media types supported by this tool. For media types, see DMUS_PMSGT_TYPES.
dwNumElements
Number of elements in the padwMediaTypes array. This value is equal to the number returned by the IDirectMusicTool8::GetMediaTypeArraySize method. If dwNumElements is less than this number, the method cannot return all the message types that are supported. If it is greater than this number, the extra elements in the array should be set to 0.
Return Values
Return values are determined by the implementation. If the method succeeds, it returns S_OK, or S_FALSE if the method could not fill in all values because dwNumElements was too small. If it fails, the method can return one of the error values shown in the following table.
| Return code |
| E_POINTER |
| E_INVALIDARG |
| E_NOTIMPL |
Remarks
If the method returns E_NOTIMPL, the tool processes all media types.
