Access violation

I have a global CRITICAL_SECTION object, but when I try to use EnterCriticalSection() with it, I get an access violation.

CRITICAL_SECTION g_criticalSection;
...

//Then later on in a global function I have
EnterCriticalSection(&g_criticalSection);  // Access violation here
memset(g_szClipboard,0,sizeof(g_szClipboard));
LeaveCriticalSection(&g_criticalSection);

What could be the problem?

Have you used

InitializeCriticalSection (  g_criticalSection);

before using it? If not, this would explain the problem...
