IPin::Connect

Windows CE .NET

This method initiates a connection from this pin to the other pin.

HRESULT Connect(
  IPin* pReceivePin,
  const AM_MEDIA_TYPE* pmt
);

Parameters

pReceivePin
[in] Other pin to connect to.
pmt
[in] Type to use for the connections (optional).

Return Values

Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.

Value Description
E_FAIL Failure.
E_POINTER Null pointer argument.
E_INVALIDARG Invalid argument.
E_NOTIMPL Method is not supported.
S_OK or NOERROR Success.

Remarks

This method calls the IPin::ReceiveConnection method for the other pin. The IPin::Connect method verifies that the connection is possible and might reject it. This pin proposes a media type to the other pin.

This method is implemented in the base classes by CBasePin::Connect.

Applications should not use this method. Instead, use IFilterGraph::ConnectDirect, which will use this method. Changing connections underneath the filter graph manager can cause commands to be distributed incorrectly and can cause a deadlock.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
