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.
