Description

This function will attempt to convert a given value into a pointer data type, where the value must be either a real, a string, an int64, an int32, or a ptr. Anything else will cause the game to crash with an error message.

Syntax:

ptr(n);

Arguments:

Argument	Description
n	The value to convert.

Returns:

Pointer

Example:

if !is_ptr(val)
   {
   val = ptr(application_surface);
   }

The above code checks the variable "val" to see if it contains a pointer and if it does not then one is assigned to it.
