multi thread, example on win32 is wrong?

[Lu zhuiyue]

the documentation (http://www.openssl.org/docs/crypto/threads.html) says
to use openssl library in multi threds environments,  the user should set
thses tow callback functions
locking_function and threadid_func

the example:
*crypto/threads/mttest.c*
on win32 platform:

it does not set threadid_func. it is an error?

static HANDLE *lock_cs;

void thread_setup(void)
	{
	int i;

	lock_cs=OPENSSL_malloc(CRYPTO_num_locks() * sizeof(HANDLE));
	for (i=0; i<CRYPTO_num_locks(); i++)
		{
		lock_cs[i]=CreateMutex(NULL,FALSE,NULL);
		}

	CRYPTO_set_locking_callback((void (*)(int,int,char *,int))win32_locking_callback);
	/* id callback defined */
	}

void thread_cleanup(void)
	{
	int i;

	CRYPTO_set_locking_callback(NULL);
	for (i=0; i<CRYPTO_num_locks(); i++)
		CloseHandle(lock_cs[i]);
	OPENSSL_free(lock_cs);
	}

void win32_locking_callback(int mode, int type, char *file, int line)
	{
	if (mode & CRYPTO_LOCK)
		{
		WaitForSingleObject(lock_cs[type],INFINITE);
		}
	else
		{
		ReleaseMutex(lock_cs[type]);
		}
	}

void do_threads(SSL_CTX *s_ctx, SSL_CTX *c_ctx)
	{
	double ret;
	SSL_CTX *ssl_ctx[2];
	DWORD thread_id[MAX_THREAD_NUMBER];
	HANDLE thread_handle[MAX_THREAD_NUMBER];
	int i;
	SYSTEMTIME start,end;

	ssl_ctx[0]=s_ctx;
	ssl_ctx[1]=c_ctx;

	GetSystemTime(&start);
	for (i=0; i<thread_number; i++)
		{
		thread_handle[i]=CreateThread(NULL,
			THREAD_STACK_SIZE,
			(LPTHREAD_START_ROUTINE)ndoit,
			(void *)ssl_ctx,
			0L,
			&(thread_id[i]));
		}

	printf("reaping\n");
	for (i=0; i<thread_number; i+=50)
		{
		int j;

		j=(thread_number < (i+50))?(thread_number-i):50;

		if (WaitForMultipleObjects(j,
			(CONST HANDLE *)&(thread_handle[i]),TRUE,INFINITE)
			== WAIT_FAILED)
			{
			fprintf(stderr,"WaitForMultipleObjects failed:%d\n",GetLastError());
			exit(1);
			}
		}
	GetSystemTime(&end);

	if (start.wDayOfWeek > end.wDayOfWeek) end.wDayOfWeek+=7;
	ret=(end.wDayOfWeek-start.wDayOfWeek)*24;

	ret=(ret+end.wHour-start.wHour)*60;
	ret=(ret+end.wMinute-start.wMinute)*60;
	ret=(ret+end.wSecond-start.wSecond);
	ret+=(end.wMilliseconds-start.wMilliseconds)/1000.0;

	printf("win32 threads done - %.3f seconds\n",ret);
	}
