C++ wrapper for processing UNIX signals.

It is developed according to the common approach for multi-threaded programs.

Interface:

Block all UNIX signals. Should be called before creating any threads.

void init()

---

Set function for handling UNIX signal.

void setHandler(int signum, std::function<void()> handler, bool terminate = false)

---

Listen the unix signals. Blocks current thread. It can be unblocked if handler with flag terminate=true was triggered.

void listen()

---

Set signal that terminates listening (without handler)

void setTerminateSignal(int signum)

---

Set ignoring of a signal. Equals to: signal(signum, SIG_IGN);

void setSigIgnore(int signum)

---

Set timeout handler. The handler will be called by timeout if no signals are received.

void setTimeoutHandler(uint timeout, std::function<void()> handler)

---

Build and Run example:

g++ example.cpp -o unix_example -pthread
./unix_example
pkill unix_example (from other terminal)
