Subject: tests/tests1: fix printf format for size_t arguments
X-Git-Tag: json-c-0.13-20171207~155^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F232%2Fhead;p=thirdparty%2Fjson-c.git

tests/tests1: fix printf format for size_t arguments

Change %d to %llu and add cast to unsigned long long for size_t arguments,
otherwise compilation will fail with errors like:

test1.c:70:15: error: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘size_t {aka long unsigned int}’ [-Werror=format=]

%zu is avoided to stay compatible with old libc versions (like old Visual
Studio).
