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?
