From 645749ef98612340b11c4bf2ba856e1fa469912b Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Wed, 20 Sep 2000 13:55:50 +0000 Subject: On VMS, stdout may very well lead to a file that is written to in a 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. --- apps/rand.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'apps/rand.c') diff --git a/apps/rand.c b/apps/rand.c index fa9bc023f4..04764d7ffb 100644 --- a/apps/rand.c +++ b/apps/rand.c @@ -101,7 +101,15 @@ int MAIN(int argc, char **argv) if (outfile != NULL) r = BIO_write_filename(out, outfile); else + { r = BIO_set_fp(out, stdout, BIO_NOCLOSE | BIO_FP_TEXT); +#ifdef VMS + { + BIO *tmpbio = BIO_new(BIO_f_linebuffer()); + out = BIO_push(tmpbio, out); + } +#endif + } if (r <= 0) goto err; -- cgit v1.2.3
