bool empty() const noexcept; | (since C++23) |
Checks if the stacktrace has no stacktrace entries.
Parameters

Return value
true if the stacktrace is empty, false otherwise.
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:
