Hello,

I'm coding a little OpenGL program in FASM and I need to add "wglSwapIntervalEXT" function and disable/enable vertical synch.

Does anyone know how to convert this C code into FASM ?

Code:
typedef void (APIENTRY *PFNWGLEXTSWAPCONTROLPROC)(int);
static PFNWGLEXTSWAPCONTROLPROC wglSwapIntervalEXT = NULL;

wglSwapIntervalEXT = (PFNWGLEXTSWAPCONTROLPROC)wglGetProcAddress("wglSwapIntervalEXT");    


Any help will be much appreciated Smile

havent tested it, but i imagine like this

Code:
wglSwapIntervalEXT_Name db "wglSwapIntervalEXT", 0
wglSwapIntervalEXT rd 1

push wglSwapIntervalEXT_Name
invoke wglGetProcAddress
mov [wglSwapIntervalEXT], eax

; wglSwapIntervalEXT is defined as a function pointer
; to call it...
call [wglSwapIntervalEXT]

Thank you very much wisepenguin, it works fine Smile


Code:
stdcall [wglSwapIntervalEXT],1  ; to enable OGL vertical sync
stdcall [wglSwapIntervalEXT],0  ; to disable OGL vertical sync
