Function Documentation

dsi_free()

void dsi_free

(

DSI *

dsi

)

Free any allocated resources of the master afpd DSI objects and close server socket

dsi_init_buffer()

void dsi_init_buffer ( DSI * dsi )

static

Allocate DSI read buffer and read-ahead buffer

dsi_tcp_close()

void dsi_tcp_close ( DSI * dsi )

static

dsi_tcp_init()

int dsi_tcp_init	(	DSI *	dsi,
		const char *	hostname,
		const char *	inaddress,
		const char *	inport )

Initialize DSI over TCP

Parameters

dsi	(rw) DSI handle
hostname	(r) pointer to hostname string
inaddress	(r) Optional IPv4 or IPv6 address with an optional port, may be NULL
inport	(r) pointer to port string

Creates listening AFP/DSI socket. If the parameter inaddress is NULL, then we listen on the wildcard address, i,e, on all interfaces. That should mean listening on the IPv6 address "::" on IPv4/IPv6 dual stack kernels, accepting both v4 and v6 requests.

If the parameter inaddress is not NULL, then we only listen on the given address. The parameter may contain a port number using the URL format for address and port:

IPv4, IPv4:port, IPv6, [IPv6], [IPv6]:port

Parameter inport must be a valid pointer to a port string and is used if the inaddress parameter doesn't contain a port.

Returns

0 on success, -1 on failure

dsi_tcp_listen()

int dsi_tcp_listen ( const char * address, const char * port, struct addrinfo * hints, DSI * dsi, bool * psocket_err_afnotsup )

dsi_tcp_open()

static

guess_interface()
