Bug#354310: zlib1g-dev: doc gzclose versus gzerror
Package: zlib1g-dev Version: 1:1.2.3-9 Severity: wishlist In /usr/include/zlib.h, the description of gzclose says The return value is the zlib error number (see function gzerror below). This confused me into thinking I could call gzerror after gzclose to get a string description for the error code, but if I'm not mistaken that's not allowed (gzclose obviously frees everything of the gzFile pointer). It'd be nice if the wording was clearer. I guess it's trying to say that the return from gzclose is the same sort of error code number as you get back from gzerror, not that you can or should use the latter. The thing that made me go to gzerror was of course that it gives a string description. Maybe gzclose could note that you can't get a string for its error (assuming that's in fact the case). -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i586) Shell: /bin/sh linked to /bin/dash Kernel: Linux 2.6.15-1-486 Locale: LANG=en_AU, LC_CTYPE=en_AU (charmap=ISO-8859-1) Versions of packages zlib1g-dev depends on: ii libc6-dev [libc-dev] 2.3.5-12.1 GNU C Library: Development Librari ii zlib1g1:1.2.3-9 compression library - runtime zlib1g-dev recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
