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/dsaparam.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'apps/dsaparam.c') diff --git a/apps/dsaparam.c b/apps/dsaparam.c index a15d6ea309..f861ec7b1a 100644 --- a/apps/dsaparam.c +++ b/apps/dsaparam.c @@ -205,7 +205,15 @@ bad: } } if (outfile == NULL) + { BIO_set_fp(out,stdout,BIO_NOCLOSE); +#ifdef VMS + { + BIO *tmpbio = BIO_new(BIO_f_linebuffer()); + out = BIO_push(tmpbio, out); + } +#endif + } else { if (BIO_write_filename(out,outfile) <= 0) @@ -347,7 +355,7 @@ bad: ret=0; end: if (in != NULL) BIO_free(in); - if (out != NULL) BIO_free(out); + if (out != NULL) BIO_free_all(out); if (dsa != NULL) DSA_free(dsa); EXIT(ret); } -- cgit v1.2.3
