Is there any standard C++ function for generating a substr up until a new-line char?

I was wondering if there is any standard C++ function for generating a substring up until the first '\n' character read in a source string passed to the function, after a position specified in the string? If not, I guess I'll have to write my own.

I noticed that the string::substr() function only allows you to pass a starting pos, and the length, and the substring generated will include any new-line characters it encounters before the end of length, and I can't have that, so that's why I'm looking for an alternative function to do what I specified above.

Why not use find to tell you where the \n character is, and pass that to substr?

So get the length of the string
find the starting position of your substring
*subtract 1* to avoid transferring the newline at the end.

Good idea. I didn't think of that.

Thanks.

So what I got is:

Code:

---

vector<string> C_script_operations::findJsFunctionsNames(string& scriptStr) {

    vector<string> result_vec;
    string search_str = "function";
    string current_function_name;
    size_t last_function_keyword_pos = scriptStr.find_last_of(search_str, scriptStr.size());
    if (last_function_keyword_pos != string::npos) {
        for (size_t i = scriptStr.find(search_str, 0); i < last_function_keyword_pos; i = scriptStr.find(search_str, i+1)) {
            if (i != string::npos) {
                current_function_name = stripStr(scriptStr.substr(scriptStr.find_last_of(search_str, i + search_str.size() - 1),
                                                  scriptStr.find('\n', i + search_str.size() - 1)), "function", "\n", 1, exclusive);
                if (!current_function_name.empty()) {
                    removeSpcsFromStr(current_function_name);
                    result_vec.push_back(current_function_name);
                }
            }
        }
    }
    return result_vec;

}

So I'm off now to go test my function...
