From 02fe3ca2349e45eee6dff6ca46bf9a9187f382c5 Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Sun, 23 Jun 2019 23:52:03 +0200 Subject: [PATCH] bzip2.c (testStream): Remove set, but not used nread variable. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Modern GCC warns: bzip2.c: In function ‘testStream’: bzip2.c:557:37: warning: variable ‘nread’ set but not used [-Wunused-but-set-variable] Int32 bzerr, bzerr_dummy, ret, nread, streamNo, i; ^~~~~ GCC is correct. In testStream we don't care about the number of bytes read by BZ2_bzRead. So just remove the variable and the assignment. --- bzip2.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/bzip2.c b/bzip2.c index 59f59ff..854a2bb 100644 --- a/bzip2.c +++ b/bzip2.c @@ -554,7 +554,7 @@ static Bool testStream ( FILE *zStream ) { BZFILE* bzf = NULL; - Int32 bzerr, bzerr_dummy, ret, nread, streamNo, i; + Int32 bzerr, bzerr_dummy, ret, streamNo, i; UChar obuf[5000]; UChar unused[BZ_MAX_UNUSED]; Int32 nUnused; @@ -577,7 +577,7 @@ Bool testStream ( FILE *zStream ) streamNo++; while (bzerr == BZ_OK) { - nread = BZ2_bzRead ( &bzerr, bzf, obuf, 5000 ); + BZ2_bzRead ( &bzerr, bzf, obuf, 5000 ); if (bzerr == BZ_DATA_ERROR_MAGIC) goto errhandler; } if (bzerr != BZ_STREAM_END) goto errhandler; -- 1.8.3.1
