Field Documentation

int explain_output_t::exit_has_been_used

POSIX and the C standard both say that it should not call 'exit', because the behavior is undefined if 'exit' is called more than once. So we call '_exit' instead of 'exit'.

This important if a libexplain funcion is called by an atexit hander, where exit has been called by libexplain.

struct explain_output_vtable_t* explain_output_t::vtable

The vtable instance variable is used to remember the location if this instance's class's method pointers.
