[mythtv] HandleGetNextFreeRecorder question

In programs/mythbackend/mainserver.cpp is a function called
'HandleGetNextFreeRecorder". The main part of this function is a loop
that looks at each of the recorders in 'encoderList'. Before entering
the list the function sets the value of two iterators, 'iter' and
'curr', and sets 'retval' to -1. It looks at each encoder in the list to
see if it is available. If an encorder is free, the function sets the
value of 'retval' to a positive value and continues looping through the
list until 'iter' is once again equal to 'curr';
Since the function check the value of 'retval' to see if it equals -1
before checking each recorder, the function doesn't check for any free
encoders after it has found one that is free.
Would it not be possible to break out of the loop once the function has
found a free encoder? .... Is there a reason the function
continues to loop through the rest of the list? .... What logic am
I missing here?
There is similar logic in a function called 'HandleGetFreeRecorder' in
the same file, but there is an additional check for 'lastcard' in the
loop of this function. Would breaking out of the loop in
'HandleGetFreeRecorder' cause the 'lastcard' logic not to work?
