Question

I try to initialize a mutex (VS 2008/windows xp sp2), but each time I run my app, the line:

pthread_mutex_init(&mutex, NULL);

gives me the following error:

0xC0000096: Privileged instruction.

I declare my mutex with:

static pthread_mutex_t mutex;

I tried to not call pthread_mutex_init declaring my mutex like:

static pthread_mutex_t mutex= PTHREAD_MUTEX_INITIALIZER;

but

pthread_mutex_lock(&mutex);

crash with the 0xC0000096: Privileged instruction error.

What am I doing wrong ?

On Windows, you must use the CreateMutex API to initialize a mutex object.
Or you can use the new C++ mutex class, provided your compiler supports it.
