SetStdHandle
The SetStdHandle
function is used to set the handle for the standard input, standard output, or
standard error device. The specified handle can be used by subsequent calls to
the GetStdHandle
function to refer to the input, output, or error device.
BOOL SetStdHandle(
|
DWORD nStdHandle, |
// input, output,
or error device |
|
HANDLE hHandle |
// handle to be a
standard handle |
|
); |
|
Parameters
nStdHandle
Specifies the
handle to be set. This parameter can have 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
Supplies the

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 of a console s input
buffer. Similarly, you can specify the CONOUT$ value to get a handle of the
console s active screen buffer.
