Detailed Description

This file defines a signal handler used by VPR to catch SIGINT signals (ctrl-C from terminal) on POSIX systems. It is only active if VPR_USE_SIGACTION is defined.

If a SIGINT occur the handler sets the 'forced_pause' flag of the VPR context. If 'forced_pause' is still true when another SIGINT occurs an exception is thrown (typically ending the program).
