i just cant get what this line means

VSTCALLBACK its like a global am i wrong ??? what about cdecl ?

#define VSTCALLBACK __cdecl

[Whovian]

That's a preprocessor macro definition. Whenever the compiler encounters VSTCALLBACK, it replaces it with __cdeci and compiles that instead.

[codekiddy]

__cdecl is microsoft extension which is a calling convention.

for example:
void VSTCALLBACK f() {}

is same as:
void __cdecl f() { }

that's useful in DLL's and similar.

others are:

_thiscall
_fastcall
_stdcall

you can find more info about calling conventions on MSDN web pages.
