IPMT::QueryMPEInfo method (mpeg2psiparser.h)

[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
