afp_closevol()

int afp_closevol	(	AFPObj *	obj,
		char *	ibuf,
		size_t	ibuflen,
		char *	rbuf,
		size_t *	rbuflen )

afp_getsrvrparms()

int afp_getsrvrparms	(	AFPObj *	obj,
		char *	ibuf,
		size_t	ibuflen,
		char *	rbuf,
		size_t *	rbuflen )

afp_getvolparams()

int afp_getvolparams	(	AFPObj *	obj,
		char *	ibuf,
		size_t	ibuflen,
		char *	rbuf,
		size_t *	rbuflen )

afp_openvol()

		char *	ibuf,
		size_t	ibuflen,
		char *	rbuf,
		size_t *	rbuflen )

		char *	rbuf,
		size_t *	rbuflen )

close_all_vol()

void close_all_vol ( const AFPObj * obj )

extern

closevol()

void closevol ( const AFPObj * obj, struct vol * vol )

extern

cnid_volume_reset()

void cnid_volume_reset ( const struct vol * vol )

extern

Announce a CNID table reset and end this session.

Only the session that reset the table sends the hint; a responder that re-broadcast would loop between children. No AFP attention exists for "the ID space was recycled" — the protocol guarantees IDs are never reused — so the disconnect is the signal.

cnid_volume_tag()

uint32_t cnid_volume_tag ( const struct vol * vol )

extern

Stable cross-process identifier for a volume's CNID table.

v_vid is per-process, so the same vid names different volumes in different children. v_uuid is what every child agrees on.

Returns

FNV-1a of v_uuid, or 0 if the volume has no UUID

pollvoltime()

int pollvoltime ( AFPObj * obj )

extern

poll if a volume is changed by other processes.

Parameters

obj	AFP connection object

Returns

0 no attention msg sent, 1 attention msg sent, -1 error (socket closed)

Note

if attention return -1 no packet has been sent because the buffer is full, we don't care either there's no reader or there's a lot of traffic and another pollvoltime will follow

setvoltime()

void setvoltime ( AFPObj * obj, struct vol * vol )

extern

ustatfs_getvolspace()

int ustatfs_getvolspace ( const struct vol * vol, VolSpace * bfree, VolSpace * btotal, uint32_t * bsize )

extern

Get the free space on a partition.
