Function Documentation

block_sig()

void block_sig ( DSI * dsi )

static

buf_read()

ssize_t buf_read ( DSI * dsi, uint8_t * buf, size_t count )

static

dsi_buffered_stream_read()

size_t dsi_buffered_stream_read ( DSI * dsi, uint8_t * data, const size_t length )

static

dsi_disconnect()

int dsi_disconnect

(

DSI *

dsi

)

Communication error with the client, enter disconnected state

1. close the socket
2. set the DSI_DISCONNECTED flag, remove possible sleep flags

Returns

0 if successfully entered disconnected state -1 if ppid is 1 which means afpd master died or euid == 0 i.e. where still running as root (unauthenticated session)

dsi_header_pack_reply()

void dsi_header_pack_reply ( const DSI * dsi, char * buf )

static

dsi_peek()

int dsi_peek ( DSI * dsi )

static

dsi_stream_read()

size_t dsi_stream_read	(	DSI *	dsi,
		void *	data,
		const size_t	length )

dsi_stream_receive()

int dsi_stream_receive

(

DSI *

dsi

)

Read DSI command and data

Parameters

dsi	(rw) DSI handle

Returns

DSI function on success, 0 on failure

dsi_stream_send()

int dsi_stream_send	(	DSI *	dsi,
		void *	buf,
		size_t	length )

dsi_stream_write()

ssize_t dsi_stream_write	(	DSI *	dsi,
		void *	data,
		const size_t	length,
