IWMReaderNetworkConfig::GetProxyExceptionList method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The GetProxyExceptionList method retrieves the list of computers, domains, or addresses for which the reader object bypasses the proxy server.

Syntax

HRESULT GetProxyExceptionList(
  [in]      LPCWSTR pwszProtocol,
  [out]     WCHAR   *pwszExceptionList,
  [in, out] DWORD   *pcchExceptionList
);

Parameters

[in] pwszProtocol

Pointer to a string that contains a protocol name, such as "http" or "mms". The string is not case-sensitive.

[out] pwszExceptionList

Pointer to a buffer that receives a string containing the exception list. The returned string is a comma-separated list. For more information, see SetProxyExceptionList. The list applies only to the protocol specified in pwszProtocol; the reader object supports separate settings for each protocol.

[in, out] pcchExceptionList

On input, pointer to a variable specifying the size of the pwszExceptionList buffer, in characters. On output, the variable contains the length of the string, including the terminating null character.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_INVALIDARG	NULL or invalid argument passed in.
ASF_E_BUFFERTOOSMALL	The size of the buffer passed in is not large enough to hold the return string.

Remarks

Call this method twice. The first time, pass NULL as the value for pwszExceptionList. The method returns the size of the string in the pcchExceptionList parameter. Allocate the required amount of memory for the string and call the method again. This time, pass a pointer to the allocated buffer in the pwszExceptionList parameter.

For more information, see the Remarks for SetProxyExceptionList.
