Yes, there is such a guarantee - because that’s how the input to 
“ByteStreamMultiFileSource::createNew()" is *defined*.  See the comment at line 
33 of “liveMedia/include/ByteStreamMultiFileSource.hh”:
        // A 'filename' of NULL indicates the end of the array

In other words, the input parameter “fileNameArray” is required to have a NULL 
at the end.

This makes no sense.

There is no bug in the current code, so it will not be changed.  (In the next 
release of the code, I will, however, change the comments near the beginning of 
"include/ByteStreamMultiFileSource.hh” and “ByteStreamMultiFileSource.cpp” to 
explain even more clearly the requirements of the input “fileNameArray” 
parameter.)
