Function Documentation

int check_password	(	char *	typed,
		char *	crypted
	)

Check if typed password and crypted password in the player file are the same.

Parameters:

typed	The typed password.
crypted	Crypted password from file.

Returns:

1 if the passwords match, 0 otherwise.

Definition at line 135 of file main.c.

char* clean_path

(

const char *

file

)

Takes a path and replaces all / with $.

We use strncpy so that we do not change the original string.

Parameters:

file	Path to clean.

Returns:

Cleaned up path.

Definition at line 346 of file main.c.

void clean_tmp_files

(

)

Clean temporary map files.

Definition at line 1087 of file main.c.

void cleanup

(

)

Clean up everything before exiting.

Definition at line 1116 of file main.c.

char* crypt_string	(	char *	str,
		char *	salt
	)

Encrypt a string. Used for password storage on disk.

Parameters:

str	The string to crypt.
salt	Salt, if NULL, random will be chosen.

Returns:

The crypted string.

Definition at line 104 of file main.c.

static void dequeue_path_requests

(

)

[static]

Dequeue path requests.

Todo:

Only compute time if there is something more in the queue, something like if (path_request_queue_empty()) { break; }

Definition at line 1146 of file main.c.

static void do_specials

(

)

[static]

Collection of functions to call from time to time.

Definition at line 1312 of file main.c.

void enter_exit	(	object *	op,
		object *	exit_ob
	)

Tries to move object to exit object.

Parameters:

op	Player or monster object using the exit.
exit_ob	Exit object (boat, exit, etc). If NULL, then CONTR(op)->maplevel contains that map to move the object to, which is used when loading the player object.

Definition at line 530 of file main.c.

static void enter_map	(	object *	op,
		mapstruct *	newmap,
		int	x,
		int	y,
		int	pos_flag
	)		[static]

Moves the player from current map (if any) to new map. map, x, y must be set.

If default map coordinates are to be used, then the function that calls this should figure them out.

Parameters:

op	The object we are moving
newmap	Map to move the object to - it could be the map he just came from if the load failed for whatever reason.
x	X position on the new map
y	Y position on the new map
pos_flag	If set, the function will not look for a free space and move the object, even if the position is blocked.

Definition at line 203 of file main.c.

void enter_player_savebed

(

object *

op

)

This is a basic little function to put the player back to his savebed. We do some error checking - it's possible that the savebed map may no longer exist, so we make sure the player goes someplace.

Parameters:

op	The player object entering his savebed.

Definition at line 146 of file main.c.

static void enter_random_map	(	object *	pl,
		object *	exit_ob
	)		[static]

The player is trying to enter a randomly generated map. In this case, generate the random map as needed.

Parameters:

pl	The player object entering the map.
exit_ob	Exit object the player entered from.

Definition at line 409 of file main.c.

static void enter_unique_map	(	object *	op,
		object *	exit_ob
	)		[static]

Code to enter/detect a character entering a unique map.

Parameters:

op	Player object entering the map
exit_ob	Exit object the player is entering from

Definition at line 454 of file main.c.

void fatal

(

int

err

)

Meant to be called whenever a fatal signal is intercepted. It will call the emergency_save() and the clean_tmp_files() functions.

Parameters:

err	Error level.

Definition at line 61 of file main.c.

static void iterate_main_loop

(

)

[static]

Iterate the main loop.

Definition at line 1347 of file main.c.

void leave_map

(

object *

op

)

All this really is is a glorified remove_object that also updates the counts on the map if needed and sets map timeout if needed.

Parameters:

op	The object leaving the map.

Definition at line 177 of file main.c.

int main	(	int	argc,
		char **	argv
	)

The main function.

Parameters:

argc	Number of arguments.
argv	Arguments.

Returns:

0.

Definition at line 1393 of file main.c.

void process_events

(

mapstruct *

map

)

Process objects with speed, like teleporters, players, etc.

Parameters:

map	If not NULL, only process objects on that map.

Definition at line 924 of file main.c.

static void process_players1

(

)

[static]

Do all player-related stuff before objects have been updated.

See also:

process_players2().

Definition at line 769 of file main.c.

static void process_players2

(

)

[static]

Do all player-related stuff after objects have been updated.

See also:

process_players1().

Definition at line 902 of file main.c.

void set_map_timeout

(

mapstruct *

map

)

Sets map timeout value.

Parameters:

map	The map to set the timeout for.

Definition at line 318 of file main.c.

int swap_apartments	(	const char *	mapold,
		const char *	mapnew,
		int	x,
		int	y,
		object *	op
	)

Swap one apartment (unique) map for another.

Parameters:

mapold	Old map path.
mapnew	Map to switch for.
x	X position where player's items from old map will go to.
y	Y position where player's items from old map will go to.
op	Player we're doing the switching for.

Returns:

1 on success, 0 on failure.

Definition at line 1198 of file main.c.

static char * unclean_path

(

const char *

src

)

[static]

Takes a path and replaces all $ with /.

This basically undoes clean_path().

We use strncpy so that we do not change the original string.

We are smart enough to start after the last / in case we are getting passed a string that points to a unique map path.

Parameters:

src	The path to unclean.

Returns:

Uncleaned up path.

Definition at line 375 of file main.c.

void version

(

object *

op

)

Shows version information.

Parameters:

op	If NULL the version is logged using LOG(), otherwise it is shown to the player object using new_draw_info_format().

Definition at line 80 of file main.c.
