account_add_player_cmd()

void draw_ext_info	(	int	flags,
		int	pri,
		const object *	pl,
		uint8_t	type,
		uint8_t	subtype,
		const char *	txt
	)

Sends message to player(s).

Parameters

flags	Various flags - mostly color, plus a few specials. If NDI_ALL or NDI_ALL_DMS is set, pl is ignored and the message is resent to all players or all DMs individually.
pri	Priority. The lower the value, the more important it is. Thus, 0 gets sent no matter what. Otherwise, the value must be less than the listening level that the player has set. Unfortunately, there is no clear guideline on what each level does what.
pl	Who to send the message to. pl may be NULL, particularly if flags has NDI_ALL or NDI_DMS set since it is ignored in that case. If NDI_ALL and NDI_DMS are not set, when pl is NULL, nobody gets the message. This is sometimes useful when a function that can be invoked by a player is automatically called by some other mechanism. For example, if a player tries to put something in a container, they should get a message that tells them they cannot put it in an unsuitable container, but when auto-pickup is at work, all containers are tried, even unsuitable ones, and so messages should not be sent to the player.
type	The type MSG_TYPE for the type of message.
subtype	The subtype of the message.
message	The message to send.

Those are dummy functions defined to resolve all symboles. Added as part of glue cleaning. Ryo 2005-07-15

draw_ext_info_format()

void draw_ext_info_format	(	int	flags,
		int	pri,
		const object *	pl,
		uint8_t	type,
		uint8_t	subtype,
		const char *	format,
			...
	)

Sends message to player(s).

This function is the same as draw_ext_info, but takes varargs format. Otherwise, the meaning of all the fields is the same. This is perhaps not the most efficient as we do vsnprintf on both the old and newbuf, but it simplifies the code greatly since we can just call draw_ext_info.

Parameters

flags	Various flags - mostly color, plus a few specials.
pri	Priority. It is a little odd - the lower the value, the more important it is. Thus, 0 gets sent no matter what. Otherwise, the value must be less than the listening level that the player has set. Unfortunately, there is no clear guideline on what each level does what.
pl	Can be passed as NULL - in fact, this will be done if NDI_ALL is set in the flags.
type	The type MSG_TYPE for the type of message.
subtype	The type MSG_TYPE for the subtype of message.
format	The message to send, with optional format specifiers.

map_mark	Holds flags for each tile analyzed. Should have been initialized to zero before this function is called.
strength	An initial strength*2 rectangular area that we automatically see in/penetrate through.

Note: For improved magic mapping display, the space that blocks the view is now marked with value 2. Any dependencies of map_mark being nonzero have been changed to check for 1. Also, since map_mark is a char value, putting 2 in should cause no problems.

This function examines the map the player is on, and determines what is visible. 2 is set for walls or objects that blocks view. 1 is for open spaces.

metaserver2_init()

int metaserver2_init

(

This initializes the metaserver2 logic - it reads the metaserver2 file, storing the values away. Note that it may be possible/desirable for the server to re-read the values and restart connections (for example, a new metaserver has been added and you want to start updates to it immediately and not restart the server). Because of that, there is some extra logic (has_init) to try to take that into account.

Returns

1 if we will be updating the metaserver, 0 if no metaserver updates

metserver2_thread is the function called from pthread_create. it is a trivial function - it just sleeps and calls the update function. The sleep time here is really quite arbitrary, but once a minute is probably often enough. A better approach might be to do a time() call and see how long the update takes, and sleep according to that.

Parameters

(

Upon successful login/account creation, we send a list of characters associated with the account to the client - in this way, it lets the client present a nice list so that the player can choose one. Note it is important that ns->account_name is set before calling this. Note 2: Some of the operations here are not especially efficient - O(n^2) or repeating same loop instead of trying to combine them. This is not a worry as MAX_CHARACTERS_PER_ACCOUNT is a fairly low value (less than 20), so even inefficient operations don't take much time. If that value as a lot larger, then some rethink may be needed. For now, having clearer code is better than trying to save a few microseconds of execution time.
