# handleInterrupts

## Synopsis

• Usage:
handleInterrupts = b
• Inputs:
• b,
• Outputs:
• , 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.

## Description

The command line option --int has the same effect as handleInterrupts=false.

## For the programmer
