Recommendations
SIG00-A. Mask signals handled by non-interruptible signal handlers
SIG01-A. Understand implementation-specific details regarding signal handler persistence
SIG02-A. Avoid using signals to implement normal functionality
Rules
SIG30-C. Call only asynchronous-safe functions within signal handlers
SIG31-C. Do not access or modify shared objects in signal handlers
SIG32-C. Do not call longjmp() from inside a signal handler
SIG33-C. Do not recursively invoke the raise() function
SIG34-C. Do not call signal() from within interruptible signal handlers
