Re: Oddity with Win32API, RegQueryValueEx

From: Daniel B. [email protected]
I noticed something curious when using the RegQueryValueEx()
#include <windows.h>
HKEY hk;
rv = RegQueryValueEx(hk, val, NULL, NULL, buf, &size);

RegCloseKey =‘advapi32’, ‘RegCloseKey’, ‘L’, ‘L’)

if, key, 0, KEY_READ, hk) == 0
hk = hk.unpack(‘L’).first
buf = 0.chr * 1024
size = 0.chr * 4

should be
size = [buf.length].pack(‘L’)

Ah, ok. I thought it would just set the size regardless.
