handleInterrupts

• Usage:

  handleInterrupts = b

• Inputs:
  • b, a Boolean value
• Outputs:
  • a Boolean value, the value of b
• Consequences:

  • If b is false, then the default operating system actions for the signals SIGINT, and SIGALRM are restored, and thus typing CTRL-C or the triggering of an alarm will result in the Macaulay2 process terminating immediately. If b is true, then the default Macaulay2 signal handlers are installed, and thus control will be returned to top level after the code currently executing notices that the interrupt flag has been set.
