Contents

[edit] Parameters

(none)

[edit] Return value

true if the stacktrace_entry is non-empty, false otherwise.

[edit] Notes

A non-empty stacktrace_entry can be obtained from a std::basic_stacktrace created by std::basic_stacktrace::current or a copy of such std::basic_stacktrace.

An empty stacktrace_entry can be created by the default constructor.
