[support.srcloc] (original) (raw)

:

struct s { source_location member = source_location::current(); int other_member; s(source_location loc = source_location::current()) : member(loc) // values of member refer to the location of the calling function ([dcl.fct.default]) {} s(int blather) : // values of member refer to this location other_member(blather) {} s(double) // values of member refer to this location {} }; void f(source_location a = source_location::current()) { source_location b = source_location::current(); // values in b refer to this line }

void g() { f(); // f's first argument corresponds to this line of code

source_location c = source_location::current(); f(c); // f's first argument gets the same values as c, above }
