std::basic_...ce::current(3) C++ Standard Libary std::basic_...ce::current(3) NAME std::basic_stacktrace::current - std::basic_stacktrace::current Synopsis static basic_stacktrace current( const allocator_type& alloc = (1) (since C++23) allocator_type() ) noexcept; static basic_stacktrace current( size_type skip, const allocator_type& alloc = (2) (since C++23) allocator_type() ) noexcept; static basic_stacktrace current( size_type skip, size_type max_depth, (3) (since C++23) const allocator_type& alloc = allocator_type() ) noexcept; Let s[i] (0 i < n) denote the (i+1)-th stacktrace entry in the stacktrace of the current evaluation in the current thread of execution, where n is the count of the stacktrace entries in the stackentry. 1) Attempts to create a basic_stacktrace consisting of s[0], s[1], ..., s[n - 1]. 2) Attempts to create a basic_stacktrace consisting of s[m], s[m + 1], ..., s[n - 1], where m is min(skip, n). 3) Attempts to create a basic_stacktrace consisting of s[m], s[m + 1], ..., s[o - 1], where m is min(skip, n) and o is min(skip + max_depth, n). The behavior is undefined if the skip + max_depth < skip (i.e. the mathematical re- sult of skip + max_depth overflows). In all cases, alloc is stored into the created basic_stacktrace and used to allocate the storage for stacktrace entries. Parameters alloc - allocator to use for all memory allocations of the con- structed basic_stacktrace skip - the number of stacktrace entries to skip max_depth - the maximum depth of the stacktrace entries Return value If the allocation succeeds, the basic_stacktrace described above. Otherwise, an empty basic_stacktrace. Example This section is incomplete Reason: no example See also constructor creates a new basic_stacktrace (public member function) current constructs a new source_location corresponding to the location of the [static] call site (public static member function of std::source_loca- tion) Category: * Todo no example http://cppreference.com 2024.06.10 std::basic_...ce::current(3)
