// will be available in 7.x. So, the only way to suspend the
// attached-to inferior is to interrupt it directly.
// The following call will take a special path in the
// JNI code. See Java_org_eclipse_cdt_utils_spawner_Spawner_raise()
// We don't use the Cygwin 'kill' command since we don't
// know if the process associated with PID (the
// inferior) is a cygwin
// process (kill only works on cygwin programs). We also
// can't use GenerateConsoleCtrlEvent() to send a CTRL-C
// since that can only be used if the recipient shares a
// console with the caller. So, we end up looking for a
// console window associated with PID, and then we
// fabricate keyboard events to simulate the user doing
// a CTRL-C in that console! Crazy stuff, but it works.
// Thing is, the PID associated with the console window
// has to be that of the process we're trying to
// interrupt. What that means is that in order for CDT's
// 'suspend' button to work in an attach debug session,
// the inferior must have been launched with its own
// console. If you open a Windows console and type
// 'myprogram.exe', CDT can attach to it but not suspend
// it once it resumes it. Instead, you have to launch
// the program by using 'start myprogram.exe'.

// program or not
