Contoh berikut menunjukkan bagaimana sebuah utas (thread) menginisialisasi, memasuki, dan merilis bagian penting . Ini menggunakan fungsi InitializeCriticalSectionAndSpinCount, EnterCriticalSection, LeaveCriticalSection, dan DeleteCriticalSection.

// Global variable
CRITICAL_SECTION CriticalSection; 

int main( void )
{
    ...

    // Initialize the critical section one time only.
    if (!InitializeCriticalSectionAndSpinCount(&CriticalSection, 
        0x00000400) ) 
        return;
    ...

    // Release resources used by the critical section object.
    DeleteCriticalSection(&CriticalSection);
}

DWORD WINAPI ThreadProc( LPVOID lpParameter )
{
    ...

    // Request ownership of the critical section.
    EnterCriticalSection(&CriticalSection); 

    // Access the shared resource.

    // Release ownership of the critical section.
    LeaveCriticalSection(&CriticalSection);

    ...
return 1;
}
