From b5007211b6582fc38647ff695b5ac51541ea9de8 Mon Sep 17 00:00:00 2001 From: Karsten Blees Date: Thu, 27 Nov 2014 00:24:01 -0500 Subject: pack-bitmap: do not use gcc packed attribute The "__attribute__" flag may be a noop on some compilers. That's OK as long as the code is correct without the attribute, but in this case it is not. We would typically end up with a struct that is 2 bytes too long due to struct padding, breaking both reading and writing of bitmaps. Instead of marshalling the data in a struct, let's just provide helpers for reading and writing the appropriate types. Besides being correct on all platforms, the result is more efficient and simpler to read.
