Gets a direct reference to the format buffer.
|C||HRESULT IltmmMediaTypeDisp_get_Format(pMediaTypeDisp, pVal)|
Pointer to an IltmmMediaTypeDisp interface.
Pointer to a variable to be updated with a VARIANT containing a SAFEARRAY reference. The array is composed of a single dimension of bytes. This array contains the format information based on the format type.
|S_OK||The function was successful.|
|<> S_OK||An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.|
This routine will allow direct access to the format buffer for in-process servers. However, if the interface is marshaled across process boundaries, then the client will only be accessing a copy of the data. In such a case, the client should call IltmmMediaTypeDisp::SetFormatData to alter the contents of the format buffer.
The array referenced by pVal cannot be resized. To resize the format buffer, call IltmmMediaTypeDisp::put_FormatSize and then call IltmmMediaTypeDisp::get_Format again.
If the function succeeds, the caller must free the VARIANT referenced by pVal by calling the VariantClear function.
