The GetCurFile method retrieves the name and media type of the current file.
HRESULT GetCurFile( LPOLESTR *ppszFileName, AM_MEDIA_TYPE *pmt );
[out] Address of a pointer that receives the name of the file, as an OLESTR type.
[out] Pointer to an AM_MEDIA_TYPE structure that receives the media type. This parameter can by NULL, in which case the method does not return the media type.
Returns an HRESULT value. Possible values include the following.
|E_FAIL||No file is opened.|
|E_POINTER||NULL pointer argument in ppszFileName.|
If the filter has not opened a file, the method might succeed but return NULL in the ppszFileName parameter. Check the value when the method returns.
The method allocates the memory for the string returned in ppszFileName, and the memory for the format block in the media type (if any). The caller must free them by calling CoTaskMemFree. For the media type, you can use the FreeMediaType function in the base class library.
