DETAILED DESCRIPTION

Handle cpio payloads within rpm packages.

Warning: FIXME: We don't translate between cpio and system mode bits! These should both be the same, but really odd things are going to happen if that's not true!

#define GET_NUM_FIELD(phys, log)

Value:

log = strntoul(phys, &end, 16, sizeof(phys));         if ( (end - phys) != sizeof(phys) ) return CPIOERR_BAD_HEADER;

#define SET_NUM_FIELD(phys, val, space)

Value:

sprintf(space, '%8.8lx', (unsigned long) (val));         memcpy(phys, space, 8);
