代码：
```
func createPrivateNamespace(privateNamespaceAttributes *windows.SecurityAttributes, boundaryDescriptor windows.Handle, aliasPrefix *uint16) (handle windows.Handle, err error) {
r0, _, e1 := syscall.Syscall(procCreatePrivateNamespaceW.Addr(), 3, uintptr(unsafe.Pointer(privateNamespaceAttributes)), uintptr(boundaryDescriptor), uintptr(unsafe.Pointer(aliasPrefix)))
handle = windows.Handle(r0)
if handle == 0 {
if e1 != 0 {
err = errnoErr(e1)
} else {
err = syscall.EINVAL
}
}
return
}
```
