Synopsis:

int dll_printone(const dll_obj_t *restrict dll_obj,
    f_dll_obj_handler_index fn_print_idx,
    size_t idx);

bool dll_print(const dll_t *restrict dll,
    f_dll_obj_handler_index fn_print_idx);
bool dll_printr(const dll_t *restrict dll,
    f_dll_obj_handler_index fn_print_idx);

size_t dll_printn(const dll_t *restrict dll,
    f_dll_obj_handler_index fn_print_idx,
    size_t start,

Description:

• dll_print: Print all objects via fn_print_idx from begin
• dll_printr: Print all objects via fn_print_idx from end
• dll_printn: Printing at most n objects starts from index start via fn_print_idx to end of list
• dll_printnr: Printing at most n objects starts from index start via fn_print_idx to start of list

Return value:

true or count of printed objects otherwise false if:

• dll is NULL
• if DLL_BIT_EIGN is not specified:
  • fn_print_idx is NULL
  • list dll hasn't any objects
  • data inside at least 1 object is pointed to NULL
  • fn_print_idx handler returns a negative value
