[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

The QueryMPEInfo method returns the multi-protocol encapsulation (MPE) information in the PMT, if any.

Syntax

HRESULT QueryMPEInfo(
  [out] MPE_ELEMENT **ppMPEList,
  [out] UINT        *puiCount
);

Parameters

[out] ppMPEList

Address of a variable that receives a pointer to an array of MPE_ELEMENT structures. The client must free the array by calling the CoTaskMemFree function.

[out] puiCount

Receives the number of elements returned in ppMPEList.

Return value

The method returns an HRESULT. Possible values include those in the following table.

Return code	Description
E_OUTOFMEMORY	Insufficient memory.
E_POINTER	NULL pointer argument.
MPEG2_E_MALFORMED_TABLE	Malformed table.
MPEG2_S_MPE_INFO_FOUND	MPE information was found in the PMT.
MPEG2_S_MPE_INFO_NOT_FOUND	MPE information was not found in the PMT.

Remarks

If the method succeeds, it returns one of the two success codes listed in the previous table. It returns MPEG2_S_MPE_INFO_FOUND if the PMT contains MPE information, or MPEG2_S_MPE_INFO_NOT_FOUND if the PMT does not contain any MPE information.
