SQRESULT sq_getinstanceup(HSQUIRRELVM v, SQInteger idx, SQUserPointer * up, SQUSerPointer typetag);
gets the userpointer of the class instance at position idx in the stack. if the parameter 'typetag' is different than 0, the function checks that the class or a base class of the instance is tagged with the specified tag; if not the function fails. If 'typetag' is 0 the function will ignore the tag check.
- parameters:
-
- HSQUIRRELVM v
-
the target VM
- SQInteger idx
-
an index in the stack
- SQUserPointer * up
-
a pointer to the userpointer that will store the result
- SQUSerPointer typetag
-
the typetag that has to be checked, if this value is set to 0 the typetag is ignored.
