IEnumConnectionPoints::Next method (ocidl.h)

  • Článek

Retrieves the specified number of items in the enumeration sequence.

Syntax

HRESULT Next(
  [in]  ULONG             cConnections,
  [out] LPCONNECTIONPOINT *ppCP,
  [out] ULONG             *pcFetched
);

Parameters

[in] cConnections

The number of items to be retrieved. If there are fewer than the requested number of items left in the sequence, this method retrieves the remaining elements.

[out] ppCP

An array of enumerated items.

The enumerator is responsible for calling AddRef, and the caller is responsible for calling Release through each pointer enumerated. If cConnections is greater than 1, the caller must also pass a non-NULL pointer passed to lpcFetched to know how many pointers to release.

[out] pcFetched

The number of items that were retrieved. This parameter is always less than or equal to the number of items requested.

Return value

If the method retrieves the number of items requested, the return value is S_OK. Otherwise, it is S_FALSE.
