Constants

const MaxArgs = 42

MaxArgs should be divisible by 2, as Windows stack must be kept 16-byte aligned on syscall entry.

Although it only permits maximum 42 parameters, it is arguably large enough.

Functions

func AsmStdCallAddr

func AsmStdCallAddr() uintptr

AsmStdCallAddr is the address of a function that accepts a pointer to StdCallInfo stored on the stack following the C calling convention, and calls the function using Windows' stdcall calling convention. Shouldn't be called directly from Go.

func StdCall

func StdCall(fn *StdCallInfo)

Types

type StdCallInfo

type StdCallInfo struct {
	Fn   uintptr
	N    uintptr // number of parameters
	Args uintptr // parameters
	R1   uintptr // return values
	R2   uintptr
	Err  uintptr // error number
}
