std::stacktrace_entry - cppreference.com (original) (raw)

| | | | | ------------------------ | | ------------- | | class stacktrace_entry; | | (since C++23) |

The stacktrace_entry class provides operations for querying information about an evaluation in a stacktrace. Each stacktrace_entry object is either empty, or represents an evaluation in a stacktrace.

stacktrace_entry models std::regular and std::three_way_comparable<std::strong_ordering>.

[edit] Member functions

(constructor) constructs a new stacktrace_entry (public member function) [edit]
(destructor) destroys the stacktrace_entry (public member function)
operator= assigns the contents of one stacktrace_entry to another (public member function)
Observers
native_handle gets the implementation-defined native handle of the stacktrace_entry (public member function)
operator bool checks whether the stacktrace_entry is empty (public member function)
Query
description gets the description of the evaluation represented by the stacktrace_entry (public member function)
source_file gets the name of the source file that lexically contains the expression or statement whose evaluation is represented by the stacktrace_entry (public member function) [edit]
source_line gets the line number that lexically relates the evaluation represented by the stacktrace_entry (public member function) [edit]

boost::stacktrace::frame (available in Boost.Stacktrace) can be used instead when std::stacktrace_entry is not available.
