Fetch necessary function call arguments in Emacs

I started writing code in Emacs some days ago and i'm doing very well, however, a very difficult and boring situation is always annoying me, that is the moment of call a function written by me. To make the things easy i press M-/ to auto complete the function name, but sometimes there're many necessary arguments that must be supplied and it's hard to remember, my initial approach was open a new buffer, visit the file, search where the functions is positioned and see the necessary arguments. I'd like to find any feature that fetch these arguments for me, and put them in a mini buffer or in another place. Any suggestions ?
