Function Documentation

cf_func_access()

int cf_func_access	(	int *vp	__attribute__(unused),
		char *	str,
		long	extra,
		dbref	player,
		char *	cmd
	)

Set access on functions.

Parameters

vp	Not used
str	Name of function
extra	Nametab
player	DBref of player
cmd	Command

Returns

int Result

do_function()

void do_function	(	dbref	player,
		dbref cause	__attribute__(unused),
		int	key,
		char *	fname,
		char *	target
	)

Add a function.

Parameters

player	DBref of player
cause	Not used
key	Key
fname	Function name
target	Target

Check for list first

Make it case-insensitive, and look it up.

No name given, list them all.

Make a local uppercase copy of the function name

Verify that the function doesn't exist in the builtin table

Make sure the target object exists

Make sure the attribute exists

Make sure attribute is readably by me

Privileged functions require you control the obj.

See if function already exists. If so, redefine it

helper_list_funcaccess()

void helper_list_funcaccess	(	dbref	player,
		FUN *	fp
	)

Helper function for list_funcaccess.

Parameters

player	DBref of player
fp	Function

init_functab()

void init_functab

(

void

)

Initialize the function hashtable.

list_funcaccess()

void list_funcaccess

(

dbref

player

)

List function access rights.

Parameters

player

DBref of player

list_functable()

void list_functable

(

dbref

player

)

List available functions.

Parameters

player

parse_ext_access()

int parse_ext_access	(	int *	perms,
		EXTFUNCS **	xperms,
		char *	str,
		NAMETAB *	ntab,
		dbref	player,
		char *	cmd
	)

Parse an extended access list with module callouts.

Parameters

perms	Permissions
xperms	Extendes permissions
str	String buffer
ntab	Name Table
player	DBref of player
cmd	Command

Returns

CF_Result

Check for negation

Set or clear the appropriate bit

Is this a module callout?

Split it apart, see if we have anything.
