size_type size() const noexcept; |
(since C++23) |
Returns the number of entries in the stacktrace.
Parameters
(none).
Return value
The number of entries in the stacktrace.
Complexity
Constant.
Example
The following code uses size to display the number of entries in the current stacktrace:
#include <stacktrace>
#include <iostream>
int main()
{
auto trace = std::stacktrace::current();
std::cout << "trace contains " << trace.size() << " entries.\n";
}
Possible output:
