Group section

Hi Josh
I am getting error on the following code, and it looks like to be related to group sections.
As you can see I changed the dwarf_elf_init to dwarf_begin_elf, but passed NULL on the third parameter.
Do you know how should I actually deal with it? 

  91 bool DwarfHandle::init_dbg()                                                     
 92 {                                                                                
 93     //int status;                                                                
 94     //Dwarf_Error err;                                                           
 95     if (init_dwarf_status == dwarf_status_ok) {                                  
 96         return true;                                                             
 97     }                                                                            
 98                                                                                  
 99     if (init_dwarf_status == dwarf_status_error) {                               
100         return false;                                                            
101     }                                                                            
102                                                                                  
103     //status = dwarf_elf_init(file->e_elfp(), DW_DLC_READ,                       
104     //                       err_func, &file_data, &file_data, &err);            
105                                                                                  
106     file_data = dwarf_begin_elf(file->e_elfp(), DWARF_C_READ, NULL);             
107     cerr << "Error message:" << dwarf_errmsg(-1) << endl;                        
108     if (!file_data) {                                                            
109         init_dwarf_status = dwarf_status_error;                                  
110         return false;                                                            
111     }
