IDA Help: demangle_name

Demangle a name
     name - name to demangle
     disable_mask - a mask that tells how to demangle the name
                    it is a good idea to get this mask using
                    get_inf_attr(INF_SHORT_DN) or get_inf_attr(INF_LONG_DN)
Returns: a demangled name
If the input name cannot be demangled, returns 0

string demangle_name(string name, long disable_mask);
