From: Tor Lillqvist Date: Wed, 12 Mar 2008 18:33:59 +0000 (+0000) Subject: Introduce a macro GLocalFileStat that is the normal struct stat on Unix X-Git-Tag: GLIB_2_17_0~168 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1c6676396db5806f2714eefe7581e06853ce95b1;p=platform%2Fupstream%2Fglib.git Introduce a macro GLocalFileStat that is the normal struct stat on Unix 2008-03-12 Tor Lillqvist * glocalfileinfo.h: Introduce a macro GLocalFileStat that is the normal struct stat on Unix but struct _stati64 on Windows to have access to 64-bit file size information. Use that instead of struct stat in the functions declared here in this private header. * glocalfileinfo.c: Corresponding changes. Move some G_OS_WIN32, S_ISLNK and HAVE_UTIMES ifdefs and add some more to avoid compiler warnings about unused functions and variables. Don't set meaningless attributes like inode numbers on Windows. svn path=/trunk/; revision=6697 --- diff --git a/gio/ChangeLog b/gio/ChangeLog index 9b324eb..04fbda5 100644 --- a/gio/ChangeLog +++ b/gio/ChangeLog @@ -1,3 +1,15 @@ +2008-03-12 Tor Lillqvist + + * glocalfileinfo.h: Introduce a macro GLocalFileStat that is the + normal struct stat on Unix but struct _stati64 on Windows to have + access to 64-bit file size information.
