std::stackt...source_line(3) C++ Standard Libary std::stackt...source_line(3) NAME std::stacktrace_entry::source_line - std::stacktrace_entry::source_line Synopsis std::uint_least32_t source_line() const; (since C++23) Returns a 1-based line number that lexically relates to the evaluation represented by *this, or 0 on failure other than allocation failure, e.g. when *this is empty. Either source_file returns the presumed source file name and source_line returns the presumed line number, or source_file returns the actual source file name and source_line returns the actual line number. Parameters (none) Return value The line number specified above on success, 0 on failure other than al- location failure. Exceptions Throws std::bad_alloc if memory for the internal data structures cannot be allocated. Notes The presumed line number is what the predefined macro __LINE__ expands to, and can be changed by the #line directive. This section is incomplete Reason: definition of "actual line number" is missing (LWG issue 3507) This function is not required to be noexcept because getting source line requires allocation on some platforms. Example This section is incomplete Reason: no example See also line return the line number represented by this object (public member function of std::source_location) Categories: * Todo with reason * Todo no example http://cppreference.com 2024.06.10 std::stackt...source_line(3)
