A very quick test on Fedora with the hacked code seemed to do the trick.
Good.
So the compiler obviously needs the "return 0;" to be happy, but the
program actually exits on the "std::raise( SIGINT );"?
I suppose the compiler can't know if the 'raise' will terminate the
program, so it needs the 'return'.
Curious thought, a normal exit will free memory and close open files
that were missed by an inexperienced programmer like me. But will this
style exit do the same?
Good question. I had to search for the answer and it seems it does
indeed the same:
http://www.gnu.org/software/libc/manual/html_node/Termination-Internals.html
"When a process terminates for any reason -- either because the program
terminates, or as a result of a signal -- the following things happen:"
Best regards,
Antonio.
