SUMMARY
If a console process spawns another console process by using CreateProcess() with the CREATE_NEW_PROCESS_GROUP flag, the parent process cannot use GenerateConsoleCtrlEvent() to send the child process a CTRL+C signal.
MORE INFORMATION
The Platform SDK documentation for GenerateConsoleCtrlEvent() incorrectly states that this function can be used to send a CTRL+C signal to a new process group.
In fact, a process launched in a new process group does not receive CTRL+C signals.
Although new process groups cannot receive the CTRL+C signal, they can receive a CTRL+BREAK signal.
This documentation error has been corrected in the most recent version of the MSDN Library.
