readline_atexit()

void readline_atexit

(

void

)

Clear readline stuff at exit. To cater for as many different cases as possible, we call this both like any function call from server_quit() before exit(), and as a atexit handler. Former is to get everything cleared already before exit(), before any other atexit handler comes to play. Latter is to make sure that the function gets called also when in those rare cases where we exit some other way than server_quit() - that's important for always restoring terminal to a working state.

That means that in usual case this function gets called twice. Make sure that it doesn't try double frees or similar when that happens.

server_make_connection()

int server_make_connection	(	int	new_sock,
		const char *	client_addr,
		const char *	client_ip
	)

Server accepts connection from client: Low level socket stuff, and basic-initialize the connection struct. Returns 0 on success, -1 on failure (bad accept(), or too many connections).

server_open_socket()

int server_open_socket

(

void

)

Open server socket to be used to accept client connections and open a server socket for server LAN announcements.

server_sniff_all_input()

enum server_events server_sniff_all_input

(

void

)

Get and handle:

• new connections,
• input from connections,
• input from server operator in stdin

This function also handles prompt printing, via the con_prompt_* functions. That is, other functions should not need to do so. –dwp
