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

Syntax

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 Value

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.
