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 |
