record-oriented fashion. That means that every write() will write a separate record, which will be read separately by the programs trying to read from it. This can be very confusing. The solution is to put a BIO filter in the way that will buffer text until a linefeed is reached, and then write everything a line at a time, so every record written will be an actual line, not chunks of lines and not (usually doesn't happen, but I've seen it once) several lines in one record. Voila, BIO_f_linebuffer() is born. Since we're so close to release time, I'm making this VMS-only for now, just to make sure no code is needlessly broken by this. After the release, this BIO method will be enabled on all other platforms as well.
