You are correct no memory assigned. Maybe no warning for using an unitialized
variable, if turned a warning would be issued for using unitizialized variable.
Memory may be allocated with malloc but unless function
emcCommandBuffer->write(...) store the pointer internally, copy data internally
is below might be a much better idea. If state_msg variable is not used further
down or at least is not supposed the block will also limit life time of
variable.
{
EMC_TASK_SET_STATE state_msg;
state_msg.state = EMC_TASK_STATE_OFF;
state_msg.serial_number = ++emcCommandSerialNumber;
emcCommandBuffer->write(&state_msg);
}
