I'm trying to enumerate over a list of values in the Windows registry using Go, but I'm running into some trouble. I've tried two approaches: using both the Go-provided syscall library to call into RegEnumValue , as well as using a Windows API wrapper by lxn. In both cases, I'm having the same issue. This is the code I'm using (which is currently using the win library from lxn):

var root win.HKEY rootpath, _ := syscall.UTF16PtrFromString("HARDWARE\\DEVICEMAP\\SERIALCOMM") fmt.Println(win.RegOpenKeyEx(win.HKEY_LOCAL_MACHINE, rootpath, 0, win.KEY_READ, &root)) var name_length uint32 = 72 var name *uint16 var key_type uint32 var lpData *byte var lpDataLength uint32 = 72 var zero_uint uint32 = 0 fmt.Println(win.RegEnumValue(root, zero_uint, name, &name_length, nil, &key_type, lpData, &lpDataLength)) win.RegCloseKey(root)

In this case, RegEnumValue always returns code 87, which MSDN's only explanation is "The parameter is incorrect."

Does anyone have any ideas that can point me in the right direction for this?
