IEnumParticipant::Next method

[Next is not available for use in Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The RTC Client API provides similar functionality.]

The Next method gets the next specified number of elements in the enumeration sequence. This method is hidden from Visual Basic and scripting languages.

Syntax

HRESULT Next(
  [in]  ULONG         celt,
  [out] ITParticipant **ppElements,
  [out] ULONG         *pceltFetched
);

Parameters

celt [in]

Number of elements requested.

ppElements [out]

Pointer to ITAgentHandler interfaces.

pceltFetched [out]

Pointer to number of elements actually supplied. May be NULL if celt is one.

Return value

This method can return one of these values.

Return code	Description
S_OK	Method returned celt number of elements.
S_FALSE	Number of elements remaining was less than celt.
E_POINTER	The ppElements parameter is not a valid pointer.
