Detailed Description

Image related communication.

Date:

This file deals with the image related communication to the client. I've located all the functions in this file - this localizes it more, and means that we don't need to declare things like all the structures as globals.

Function Documentation

void esrv_send_face	(	socket_struct *	ns,
		short	face_num,
		int	nocache
	)

Sends a face to a client if they are in pixmap mode nothing gets sent in bitmap mode.

If nocache is true (nonzero), ignore the cache setting from the client - this is needed for the askface, in which we really do want to send the face (and askface is the only place that should be setting it). Otherwise, we look at the facecache, and if set, send the image name.

Here is the caller graph for this function:

void send_face_cmd	(	char *	buff,
		int	len,
		socket_struct *	ns
	)

Client has requested pixmap that it somehow missed getting.

This will be called often if the client is caching images.

void send_image_sums	(	socket_struct *	ns,

Sends requested face information.

Parameters:

ns	socket to send to
params	contains first and last index of face

For each image in [start..stop] sends

• checksum
• name
