SetStdHandle

The SetStdHandle function sets the handle for the standard input, standard output, or standard error device.

BOOL SetStdHandle(
  DWORD nStdHandle,  // input, output, or error device
  HANDLE hHandle     // handle
);

Parameters

nStdHandle
[in] Specifies the standard handle to be set. This parameter can be one of the following values.
Value Meaning
STD_INPUT_HANDLE Standard input handle
STD_OUTPUT_HANDLE Standard output handle
STD_ERROR_HANDLE Standard error handle

hHandle
[in] Handle to set as standard input, standard output, or standard error.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The standard handles of a process may have been redirected by a call to SetStdHandle, in which case GetStdHandle will return the redirected handle. If the standard handles have been redirected, you can specify the CONIN$ value in a call to the CreateFile function to get a handle to a console's input buffer. Similarly, you can specify the CONOUT$ value to get a handle to the console's active screen buffer.
