Recommendations
SIG00-C. Mask signals handled by noninterruptible signal handlers
SIG01-C. Understand implementation-specific details regarding signal handler persistence
SIG02-C. 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
