本文整理匯總了Golang中syscall.LazyProc類的典型用法代碼示例。如果您正苦於以下問題：Golang LazyProc類的具體用法？Golang LazyProc怎麽用？Golang LazyProc使用的例子？那麽, 這裏精選的類代碼示例或許可以為您提供幫助。
在下文中一共展示了LazyProc類的3個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的Golang代碼示例。
示例1: Wrap
func (k *Kernel) Wrap(p *syscall.LazyProc) CallFunc {
return func(args ...uintptr) error {
var r0 uintptr
var e1 syscall.Errno
size := uintptr(len(args))
if len(args) <= 3 {
buf := make([]uintptr, 3)
copy(buf, args)
r0, _, e1 = syscall.Syscall(p.Addr(), size,
buf[0], buf[1], buf[2])
} else {
buf := make([]uintptr, 6)
copy(buf, args)
r0, _, e1 = syscall.Syscall6(p.Addr(), size,
buf[0], buf[1], buf[2], buf[3], buf[4], buf[5],
)
}
if int(r0) == 0 {
if e1 != 0 {
return error(e1)
} else {
return syscall.EINVAL
}
}
return nil
}
}示例2: pulseEvent
func pulseEvent(handle syscall.Handle, proc *syscall.LazyProc) (err error) {
r0, _, _ := proc.Call(uintptr(handle))
if r0 != 0 {
err = syscall.Errno(r0)
}
return
}示例3: openEvent
func openEvent(desiredAccess uint32, inheritHandle bool, name string, proc *syscall.LazyProc) (handle syscall.Handle, err error) {
namep, _ := syscall.UTF16PtrFromString(name)
var _p2 uint32
if inheritHandle {
_p2 = 1
}
r0, _, e1 := proc.Call(uintptr(desiredAccess), uintptr(_p2), uintptr(unsafe.Pointer(namep)))
handle = syscall.Handle(r0)
if handle == syscall.InvalidHandle {
err = e1
}
return
}
