Detailed Description

Client interface main routine.

This file sets up a few global variables, connects to the server, tells it what kind of pictures it wants, adds the client and enters the main event loop (event_loop()) checks the tcp socket for input and then polls for x events. This should be fixed since you can just block on both filedescriptors.

The DoClient function receives a message (an ArgList), unpacks it, and in a slow for loop dispatches the command to the right function through the commands table. ArgLists are essentially like RPC things, only they don't require going through RPCgen, and it's easy to get variable length lists. They are just lists of longs, strings, characters, and byte arrays that can be converted to a machine independent format.

Function Documentation

void check_animation_status

(

int

anum

)

Check animation status.

Parameters:

anum	Animation ID.

Definition at line 358 of file client.c.

int cs_write_string	(	char *	buf,
		size_t	len
	)

Takes a string of data, and writes it out to the socket.

Parameters:

fd	File descriptor to send the string to.
buf	The string.
len	Length of the string.

Returns:

0 on success, -1 on failure.

Definition at line 345 of file client.c.

void DoClient

(

)

Definition at line 156 of file client.c.

sint64 GetInt64_String

(

const unsigned char *

data

)

64-bit version of GetInt_String().

Parameters:

data	The string.

Returns:

Integer from the string.

Definition at line 297 of file client.c.

int GetInt_String

(

const unsigned char *

data

)

Does the reverse of SockList_AddInt, but on strings instead.

Parameters:

data	The string.

Returns:

Integer from the string.

Definition at line 288 of file client.c.

short GetShort_String

(

const unsigned char *

data

)

Does the reverse of SockList_AddShort, but on strings instead.

Parameters:

data	The string.

Returns:

Short integer from the string.

Definition at line 310 of file client.c.

char* GetString_String	(	uint8 *	data,
		int *	pos,
		char *	dest,
		size_t	dest_size
	)

Construct a string from data packet.

Parameters:

	data	Data packet.
[out]	pos	Position in the data packet.
	dest	Will contain the string from data packet.
	dest_size	Size of 'dest'.

Returns:

'dest'.

Definition at line 322 of file client.c.

void SockList_AddChar	(	SockList *	sl,

	)

Add integer to socket list.

Parameters:

sl	Socket list.
data	Integer data.

Definition at line 243 of file client.c.

void SockList_AddShort	(	SockList *	sl,
		uint16	data
	)

Add short integer to socket list.

Parameters:

sl	Socket list.
data	Short integer data.

Definition at line 233 of file client.c.

void SockList_AddString	(	SockList *	sl,
		char *	data
	)

Add an unterminated string.

Parameters:

sl	SockList instance to add to.
data	The string to add.

Definition at line 255 of file client.c.

void SockList_AddStringTerminated	(	SockList *	sl,
		char *	data
	)

(

SockList *

sl

)

Init socket list, setting the list's len to 0 and buf to NULL.

Parameters:

sl	Socket list.
