Each of the above macro constants expands to an integer constant expression with distinct values, which represent different signals sent to the program.
| Constant | Explanation |
|---|---|
SIGTERM | termination request, sent to the program |
SIGSEGV | invalid memory access (segmentation fault) |
SIGINT | external interrupt, usually initiated by the user |
SIGILL | invalid program image, such as invalid instruction |
SIGABRT | abnormal termination condition, as is e.g. initiated by std::abort() |
SIGFPE | erroneous arithmetic operation such as divide by zero |
Additional signal names are specified by POSIX.
| sets a signal handler for particular signal (function) |
|
| runs the signal handler for particular signal (function) |
