Subject: ui: fix format specfier in vnc to avoid break in build.
X-Git-Tag: v2.9.0-rc0~121^2~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6b557d7c933442377de59b71d0d82c3ccba68b2e;p=thirdparty%2Fqemu.git

ui: fix format specfier in vnc to avoid break in build.

When building qemu after setting _VNC_DEBUG to 1 (see ui/vnc.h),
we get the following error and the build breaks:
...
ui/vnc.c: In function ‘vnc_client_io_error’:
ui/vnc.c:1262:13: error: format ‘%d’ expects argument of type ‘int’, but
             VNC_DEBUG("Closing down client sock: ret %d (%s)\n",
             ^
cc1: all warnings being treated as errors
make: *** [ui/vnc.o] Error 1
...

This patch solves this issue by fixing the print format specifier
in vnc_client_io_error() to be %zd, which corresponds to the type
of the "ret" variable.
