SIGTERM, SIGSEGV, SIGINT, SIGILL, SIGABRT, SIGFPE

Defined in header `<csignal>`
`#define SIGTERM /implementation defined/`
`#define SIGSEGV /implementation defined/`
`#define SIGINT /implementation defined/`
`#define SIGILL /implementation defined/`
`#define SIGABRT /implementation defined/`
`#define SIGFPE /implementation defined/`

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

Notes

Additional signal names are specified by POSIX.
