Greetings monks,

My ongoing attempt at creating a PerlIO::via interface to an old module that I had laying around is actually getting somewhere. However, I've run up against a bit of a stumbling block.

The format that I'm trying to read is not new-line delimited, but is rather a 2-byte exclusive rdw format. What this means is that for every record, there are two bytes that prefix it that says how long that record is. I've written a subroutine that deals with this. When called from the old OO interface, it does as I expect it would: it returns one record. However, when I write a thin wrapper around it and call it as FILL (see PerlIO::via for details), it seems to be hung up looking for a newline character which may or may not be there. This causes the program to read in multiple records which is not what I want it to do. Is there any way to tell perl that "yes...even though there is no newline character at the end, you have the entire record"?
