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.)
