Each of the above macro constants 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 | 
[edit] Notes
Additional signal names are specified by POSIX
