ds_map_empty

This function will simply return false if the specified (previously created) DS map contains any key/value pairs, or true if it does not.

Syntax:

ds_map_empty(id);

Returns:

Boolean

Example:

if ds_map_empty(inventory)
   {
   weight = 0;
   }

The above code checks to see if the DS map indexed in the variable "inventory" has any key/value pairs and if it does not it sets the variable "weight" to 0.
