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