| Defined in header | | | | ----------------------------------------------------------------------------- | | | | #define SIG_DFL /*implementation defined*/ | | | | #define SIG_IGN /*implementation defined*/ | | |

The SIG_DFL and SIG_IGN macros expand into integral expressions that are not equal to an address of any function. The macros define signal handling strategies for std::signal() function.

Constant	Explanation
SIG_DFL	default signal handling
SIG_IGN	signal is ignored
