(none)
true if the stacktrace is empty,false otherwise.
Constant.
#include <stacktrace>#include <iostream> int main(){std::cout<<std::boolalpha;std::stacktrace bktr;std::cout<<"Initially, bktr.empty(): "<< bktr.empty()<<'\n'; bktr= std::stacktrace::current();std::cout<<"After getting entries, bktr.empty(): "<< bktr.empty()<<'\n';}
Possible output:
Initially, bktr.empty(): trueAfter getting entries, bktr.empty(): false
| returns the number of stacktrace entries (public member function)[edit] |
