From 8403908bfe1951e1ae2febea230e583c57251bf7 Mon Sep 17 00:00:00 2001 From: Ian Jackson Date: Sat, 23 Apr 2016 20:52:50 +0100 Subject: [PATCH] common.h: bitmaps: Provide PRBITMASK This is a printf format specifier, a la PRIx32 et al. This avoids us having to write %#x explicitly, which would be annoying if bitmask_t ever changed its type. No use sites introduced in this commit, so no functional change yet.
