Attaches the calling process to the console of the specified process.
BOOL WINAPI AttachConsole( _In_ DWORD dwProcessId );
The identifier of the process whose console is to be used. This parameter can be one of the following values.
Use the console of the specified process.
Use the console of the parent of the current process.
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.
A process can be attached to at most one console. If the calling process is already attached to a console, the error code returned is ERROR_ACCESS_DENIED (5). If the specified process does not have a console, the error code returned is ERROR_INVALID_HANDLE (6). If the specified process does not exist, the error code returned is ERROR_INVALID_PARAMETER (87).
A process can use the FreeConsole function to detach itself from its console. If other processes share the console, the console is not destroyed, but the process that called FreeConsole cannot refer to it. A console is closed when the last process attached to it terminates or calls FreeConsole. After a process calls FreeConsole, it can call the AllocConsole function to create a new console or AttachConsole to attach to another console.
To compile an application that uses this function, define _WIN32_WINNT as 0x0501 or later. For more information, see Using the Windows Headers.
