Description Florian Weimer 2013-04-18 11:16:10 UTC

static void check_asprintf( char **strp, const char *fmt, ... )
  __attribute__((format(printf, 2, 3)));

reveals the following misuse of check_asprintf:

scl.c: In function ‘list_packages_in_collection’:
scl.c:207:2: warning: too many arguments for format [-Wformat-extra-args]
  check_asprintf(&cmd, "rpm -qa --qf=\"#%%{name}-%%{version}-%%{release}.%%{arch}\n%%{sourcerpm}\n[%%{provides}\n]\"", colname);

Comment 1 Jindrich Novy 2013-04-23 13:37:08 UTC
Hi Florian,

sorry, I don't get it. Why would you add __attribute__((format(printf, 2, 3)) to the check_asprintf() line to trigger this?

Comment 2 Florian Weimer 2013-04-23 13:48:29 UTC
The attribute allows GCC to perform additional type checking.  The warning is quite  correct because the format string does not contain "%s", so the colname is either superfluous, or something is missing from the format string.
