Functions

int cpioTrailerWrite (FSM_t fsm)
Write cpio trailer.
int cpioHeaderWrite (FSM_t fsm, struct stat *st)
Write cpio header.
int cpioHeaderRead (FSM_t fsm, struct stat *st)
Read cpio header.
const char *const cpioStrerror (int rc)

DETAILED DESCRIPTION

Structures used to handle cpio payloads within rpm packages.

Warning: Rpm's cpio implementation may be different than standard cpio. The implementation is pretty close, but it has some behaviors which are more to RPM's liking. I tried to document the differing behavior in cpio.c, but I may have missed some (ewt).
