$cons->GenerateCtrlEvent([type, processgroup])

Sends a break signal of the specified type to the specified process group. type can be one of CTRL_BREAK_EVENT or CTRL_C_EVENT, signaling, respectively, the pressing of CTRL + Break and of CTRL + C. If not specified, type defaults to CTRL_C_EVENT. processgroup is the PID of a process sharing the same console. If omitted, it defaults to 0 (the current process), which is also the only meaningful value that you can pass to this function. Returns undef on error, a nonzero value on success.
