void Request::add_line_to_multiline_header(const string_view& line,
                                           const string_view& header)

Example #2

File: formatspec.cpp Project: nerd93/oiio

static void

                string_view value, ImageIOParameter &param)

        std::string temp = value;
        // Grab the first value from it
        sscanf (temp.c_str(), type_code, &data[i]);
