Size of structure? - Programie - 20.02.2012

Hi,

my next problem.

How can I get the size of a structure (Defined with enum)?

Код:

enum myStructure
{
	StructureItem1,
	StructureItem2,
	StructureItem3
}

Using sizeof(myStructure) shows me a "Constant symbol has no size" error.

i don't believe you can get the size of a enum lol

try

Код:

new myStructure[3] =
{
	StructureItem1,
	StructureItem2,
	StructureItem3
};

if thats not what your talking please show the code where your getting the error so i can understand what your trying to do

No, I want to get the number of constants in the enum. In my example there are 3 constants, so sizeof should return 3.

My structure and array using it:

Код:

enum enum_permission
{
	PERMISSION_ADMIN,
	PERMISSION_MAPPER,
	PERMISSION_MODERATOR,
	PERMISSION_NPCADMIN,
	PERMISSION_SERVERADMIN,
	PERMISSION_TELEPORT
}

new permissions[MAX_PLAYERS][enum_permission];

And later I want to loop through the structure items:

Код:

for (new permission = 0; permission < 6; permission++)// TODO: Replace constant number (6) with anything to get size of enum_permission
{
	if (permissions[playerid][enum_permission:permission])
	{
		if (strlen(string))
		{
			format(string, sizeof(string), "%s ", string);
		}
		format(string, sizeof(string), "%s%s", string, GetPermissionName(permission));
	}
}

Is there really no way to get the size of the structure?

pawn Код:

sizeof(permissions[])

Should do the trick.

Would that not get the size of the array? Mhh I will test it.

//EDIT: Seems to work. It returns 6.

Thanks
