Michael Fabian Dirks 2870370b84 Update 2016-03-11 14:13:39 +01:00
Michael Dirks 7591ca4a03 Fixed Variable Pointers being wrong (ASM cleanup again). 2016-02-06 18:32:16 +01:00
Michael Dirks 491e11ca77 Fix GetReturnAddress 2016-02-06 00:22:24 +01:00
Michael Dirks 7af64687cc Incorrect Stack movement causing MAV and invalid Pointers. Woops. 2016-02-06 00:16:32 +01:00
Michael Dirks b12b20ff17 Fix decls including non-existent functions. 2016-01-04 03:44:09 +01:00
Michael Dirks 2941a6b740 Attempted to implement LastCalledFunctionPointer and NextCalledFunctionPointer, aborted as not useful enough and unsure how to make these user-friendly. 2016-01-04 03:43:35 +01:00
Michael Dirks 57c310b0fc - Simplify assembler instructions so that we mess around less. 2015-12-30 06:24:35 +01:00
Michael Dirks 88122a928a - Fixed BP_GetReturnAddress not returning the correct address.
- Changed BP_GetFunctionPointer to use intelligent stackframe reading instead of memory scanning (faster & safer).
2015-12-30 06:19:44 +01:00
Michael Dirks 49c7264893 Fix broken decls. 2015-12-30 05:23:34 +01:00
Michael Dirks 7cc0788e8b - Update Headers in files to match new owner.
- Update Example08.bb to be more detailed
- Added function to grab Type pointers (would previously crash).
2015-12-30 05:11:33 +01:00
Michael Dirks 95dd86e6af Add Example08 to the project, rewrite GetFunctionPointer started. 2015-12-30 04:14:53 +01:00
Michael Dirks 519cd5c577 Upgrade to VS2015, implement variable pointers.

; Example 8 - Variable-pointers
; ---------------------------------------------------------------------------- ;
; Variable-pointers are really neat. Not only can you have a single variable for
; a lot of things in many locations (even across thread) but you can pass them
; to DLLs too! This opens up Blitz to a whole new way of working with DLLs.
; Three functions were added for this, each for the respective type
; - BP_GetVariablePointerInt(Int%)
; - BP_GetVariablePointerFloat(Float#)
; - BP_GetVariablePointerType(Type.)
; (Strings are not supported sorry.)
; Integers and Floats are really simple, just declare them and grab the pointer.
Global MyInteger% = 66
Global MyFloat# = 66.6
Global Pointer% = 0
; Grab the Integer Pointer and modify the value.
Pointer = BP_GetVariablePointerInt(MyInteger)
Print "MyInteger: " + PeekMemoryInt(Pointer)
PokeMemoryInt(Pointer, 33)
Print "MyInteger: " + PeekMemoryInt(Pointer)
; Grab the Float Pointer and modify the value.
Pointer = BP_GetVariablePointerFloat(MyFloat)
Print "MyFloat: " + PeekMemoryFloat(Pointer)
PokeMemoryFloat(Pointer, 33.3)
Print "MyFloat: " + PeekMemoryFloat(Pointer)
; Types are a tiny bit harder but open up so many possibilities once you get
; used to them. Start by defining a Type, we'll use a simple one for this.
Type MyType
Field Check%
End Type
; Now create some elements that we can use when modifying the pointer
Global MyElement.MyType = New MyType
Global MyElement1.MyType = New MyType
Global MyElement2.MyType = New MyType
Global MyElement3.MyType = New MyType
MyElement\Check = -1
MyElement1\Check = $F
MyElement2\Check = $FF
MyElement3\Check = $FFF
; Store the Pointer and original element.
Pointer = BP_GetVariablePointerType(MyElement)
Local TempPointer% = PeekMemoryInt(Pointer)
; Modifying is as simple as storing a new value to the address the pointer is
; pointing at. The Int() thing is explained in Example 5.
Print "MyElement\Check: " + MyElement\Check
PokeMemoryInt(Pointer, Int(MyElement1))
Print "MyElement\Check: " + MyElement\Check
PokeMemoryInt(Pointer, Int(MyElement2))
Print "MyElement\Check: " + MyElement\Check
PokeMemoryInt(Pointer, Int(MyElement3))
Print "MyElement\Check: " + MyElement\Check
; Always return things to their original condition. Just in case.
PokeMemoryInt(Pointer, TempPointer)
Print "MyElement\Check: " + MyElement\Check
WaitKey()
; You can do some magic with this, such as iterating through types yourself by
; changing the pointer to the next element or previous element. See Example 6.
