(and our structrure packing) From: "Ozkan Sezer (sezeroz AT gmail DOT com)" To: djgpp Content-Type: text/plain; charset=UTF-8 Reply-To: djgpp AT delorie DOT com In dir.h, structs ffblk and ffblklfn are surrounded by #pragma pack(1) and #pragma pack(4), obviously with purpose of having those two structs at byte packing. But the restoration of the original packing by that #pragma pack(4) seems wrong: do we not need a #pragma pack() in there, or am I missing something? While I was there, I also noticed that for structure packing in coff.h, dir.h and dos.h we are marking every member with __attribute__((packed) instead of giving the attribute to the stucture itself. What is the reason for it? I mean, dos.h:struct _find_t can be like the following instead of what it currently is: struct _find_t { char reserved[21]; unsigned char attrib; unsigned short wr_time; unsigned short wr_date; unsigned long size; char name[256]; } __attribute__((packed)); -- O.S.
