IFileSinkFilter::GetCurFile
This method retrieves the name and media type of the current file.
HRESULT GetCurFile(
LPOLESTR* ppszFileName,
AM_MEDIA_TYPE* pmt
);
Parameters
- ppszFileName
[out] Address of a pointer that receives the name of the file, as an OLESTR type. - pmt
[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.
Return Values
Returns an HRESULT value. The following table shows some possible values.
| Value | Description |
|---|---|
| S_OK | Success. |
| E_FAIL | No file is opened. |
| E_OUTOFMEMORY | Insufficient memory. |
| E_POINTER | NULL pointer argument in ppszFileName. |
Remarks
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.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.
