std::basic_stacktrace
basic_stacktrace::size
size_type size() const noexcept;
(since C++23)
Returns the number of entries in the stacktrace.
[edit] Parameters
(none)
[edit] Return value
The number of entries in the stacktrace.
[edit] Complexity
Constant.
[edit] Example
The following code uses size to display the number of entries in the current stacktrace:
Run this code
#include <stacktrace> #include <iostream> int main() { auto trace = std::stacktrace::current(); std::cout << "trace contains " << trace.size() << " entries.\n"; }
Possible output:
trace contains 3 entries.
