Checks if the stacktrace has no stacktrace entries.
Parameters
(none).
Return value
true
if the stacktrace is empty, false

Complexity
Constant.
Example
#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(): true After getting entries, bktr.empty(): false
