std::basic_...race::empty(3)   C++ Standard Libary  std::basic_...race::empty(3)

NAME
     std::basic_stacktrace::empty - std::basic_stacktrace::empty

Synopsis
	[[nodiscard]] bool empty() const noexcept;  (since C++23)

	Checks if the stacktrace has no stacktrace entries.

Parameters
	(none)

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

Complexity
	Constant.

Example
     // Run this code

      #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
