From 595a4d439bc5976d5bdf61da6d44337b3995d967 Mon Sep 17 00:00:00 2001 From: Nick Alcock Date: Thu, 6 Jun 2019 13:59:56 +0100 Subject: libctf: explicitly cast more size_t types used in printf()s Unsigned long will always be adequate (the only cases involving an ssize_t are cases in which no error can be generated, or in which negative output would require a seriously corrupted file: the latter has been rewritten on a branch in any case). Tested on x86_64-pc-linux-gnu, x86_64-unknown-freebsd12.0, sparc-sun-solaris2.11, i686-pc-cygwin, i686-w64-mingw32. libctf/ * ctf-dump.c (ctf_dump_format_type): Cast size_t's used in printf()s.
