Data Structure Documentation

union FunctionArg

Function Argument.

This union allows for a function to accept multiple data types as parameters. Since it is marked as a transparent_union it is always passed as a 32-bit integer in the standard registers. Thus, if a function has the signature void foo(u32) it is valid to call it as foo(FunctionArg) . However, void bar(float) would expect the parameter to be in a floating-point register, thus calling bar(FunctionArg) is not valid.

Data Fields
u32	u	32-bit unsigned integer
s32	s	32-bit signed integer
f32	f	32-bit floating-point value
void *	p	pointer (32-bits)

struct FunctionCall

Describes a function call.

Allows for a function call to be stored in memory. Essentially, a function pointer with arguments.

Data Fields
void *	function	function pointer
FunctionArg	arg1	first argument of function call
FunctionArg	arg2	second argument of function call

struct Logic

Describes simple if-then logic.

Essentially captures the behavior of an if statement in a compact struct. This allows for arrays of 'logic' (if-else chain) to be stored in memory and accessed at specific times.

Data Fields
FunctionCall	condition	function that returns bool
FunctionCall	action	function to call if condition returns true
