Detailed Description

Made this either client or server specific for 0.95.2 release - getting too complicated to keep them the same, and the common code is pretty much frozen now.

static

Get an unsigned short from the stream.

Useful for checking size of server packets.

Parameters

data	The character stream to read.

Returns

The first two bytes, converted to a uint16.

Note

Currently static since it is only used in this file. Can be added to the header and made non-static if needed elsewhere

SockList_ReadPacket()

bool SockList_ReadPacket	(	GInputStream	in[static 1],
		SockList	sl[static 1],
		size_t	len,
		GError **	error
	)

Reads from the socket and puts data into a socklist.

The only processing done is to remove the initial size value. An assumption made is that the buffer is at least 2 bytes long.

Parameters

fd	Socket to read from.
sl	Pointer to a buffer to put the read data.
len	Size of the buffer allocated to accept data.

Returns

Return true if we think we have a full packet, 0 if we have a partial packet, or -1 if an error occurred.
