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 Documentation

#define GET_NUM_FIELD	(	phys,
		log		)

Value:

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

Definition at line 49 of file cpio.c.

#define SET_NUM_FIELD	(	phys,
		val,
		space		)

Value:

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