So far, I was able to call member functions which belong to a class for a struct. CEDET can give the suggestion nicely. However, for non-member functions, such as functions in C, which usually does not belong to anything i.e. functions like sort, qsort.... I can only auto-complete with CEDET if I have an instance of a class/struct. Without it, I have to type the function manually.
Is there a way to have code suggestion for such functions?
