IRTCEnumParticipants::Next (Windows Embedded CE 6.0)

1/6/2010

This method retrieves the next specified number of elements in the enumeration sequence.

Syntax

HRESULT Next( 
  ULONG celt, 
  IRTCParticipant** ppElements,
  ULONG* pceltFetched 
);

ppElements
[out] Pointer to an array of IRTCParticipant pointers. This buffer must be large enough to hold celt pointers. The call overwrites the current values in the first celt items of the array.

If the method succeeds, an object is created for each retrieved interface pointer. The caller must free these objects using Release when they are no longer being used.

pceltFetched
[in, out] Pointer to the number of elements actually fetched by the enumerator, or NULL if celt is 1. When the method returns, the array contains pceltFetched valid pointers. The caller is responsible for releasing this memory. If celt is greater than pceltFetched , the rest of array contains NULL.

This method can return an RTC_E_ constant. The following table shows additional possible return values.

Value	Description
S_FALSE	Some elements were fetched, but the total number is less than the specified number in celt parameter. The pceltFetched parameter contains the actual number of elements fetched.
S_OK	Specified number of elements were fetched.
