InitializeCriticalSection

InitializeCriticalSection initializes a critical section object.

Syntax

VOID InitializeCriticalSection(
    LPCRITICAL_SECTION lpCriticalSection
);

Parameters

lpCriticalSection

A pointer to the critical section object.

Return Value

This function does not return a value.

Remarks

The threads of a single process can use a critical section object for mutual-exclusion synchronization. The process is responsible for allocating the memory used by a critical section object, which it can do by declaring a variable of type CRITICAL_SECTION. Before using a critical section, some thread of the process must call InitializeCriticalSection to initialize the object.

Once a critical-section object has been initialized, the threads of the process can specify the object in EnterCriticalSection or LeaveCriticalSection to provide mutually exclusive access to a shared resource. For similar synchronization between the threads of different processes, use a mutex object.

A critical-section object cannot be moved or copied. The process must also not modify the object, but must treat it as logically opaque.
