std::basic_...emove_suffix(3) C++ Standard Libarystd::basic_...emove_suffix(3) NAME std::basic_string_view::remove_suffix - std::basic_string_view::re- move_suffix Synopsis constexpr void remove_suffix( size_type n ); (since C++17) Moves the end of the view back by n characters. The behavior is undefined if n > size(). Parameters n - number of characters to remove from the end of the view Return value (none) Complexity Constant. Example // Run this code #include <iostream> #include <string_view> int main() { char arr[] = {'a', 'b', 'c', 'd', '\0', '\0', '\0'}; std::string_view v(arr, sizeof arr); auto trim_pos = v.find('\0'); if(trim_pos != v.npos) v.remove_suffix(v.size() - trim_pos); std::cout << "Array: '" << arr << "', size=" << sizeof arr << '\n' << "View : '" << v << "', size=" << v.size() << '\n'; } Output: Array: 'abcd', size=7 View : 'abcd', size=4 See also remove_prefix shrinks the view by moving its start forward (C++17) (public member function) http://cppreference.com 2022.07.31 std::basic_...emove_suffix(3)
