IPin::QueryPinInfo (Windows Embedded CE 6.0)

1/6/2010

This method retrieves information about the pin.

Syntax

HRESULT QueryPinInfo(
  PIN_INFO* pInfo
);

Parameters

  • pInfo
    [out] Pointer to a PIN_INFO structure that specifies the name of the pin, a pointer to an IBaseFilter interface on its owning filter, and the direction of the pin.

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

Unlike the pin name in the IPin::QueryId method, which is used by the filter graph manager, the name in the PIN_INFO structure is intended to be read by users.

On return, the pFilter member of PIN_INFO has an outstanding reference count if it is non-NULL, and therefore should be released when the interface is no longer needed.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later
