Function Documentation

int main (  int  argc, char *  argv[] )

void HandleInt (  int  signalValue  )

Service Ctrl+C Interrupts (SIGINT signals). SIGINT signal trap for trapping Ctrl+C interrupts. Calls abortall() to immediately abort all moves in progress. See also: abortall()

void abortall (  void   )

Abort all pending moves. Uses the low-level SCLAbort() function to send the motion abort (SK = Stop/Kill) command to all microstep drives. Sending SK to an idle microstep drive has no consequences, so this shotgun approach is the simplest and safest. Invoked by the Ctrl+C interrupt handler (HandleInt()), and called at the end of the main program when the application is quitting to make sure we don't accidentally quit and leave things running. See also: HandleInt() and SCLAbort()
