I'll use the ANSI FILENAME_MAX as Eli suggested.

Is this the correct way to use cb_host_to_target_errno?

  for (i = 0; i < sizeof buf; i++)
    if ((*p++ = ARMul_SafeReadByte (state, name++)) == '\0')
      break;
  if (i == sizeof buf) {
    state->Reg[0] = -1;
    OSptr->ErrorNo = cb_host_to_target_errno(sim_callback, ENAMETOOLONG);
    return;
  }
