[Win32 Thread] CreateMutex

CreateMutex

Win32 CreateMutex函式的原型如下:

HANDLE WINAPI CreateMutex(
__in_opt LPSECURITY_ATTRIBUTES lpMutexAttributes,
__in BOOL bInitialOwner,
__in_opt LPCTSTR lpName
); HANDLE hMutex;

lpMutexAttributes: 指向安全屬性的指標 default security attributes

bInitialOwner: 初始化互斥物件的所有者 initially not owned

lpName: 指向互斥物件名的指標 unnamed mutex

hMutex = CreateMutex(NULL, false, "LOCK");

宣告

WaitForSingleObject(hMutex, INFINITE);

Lcok

ReleaseMutex(hMutex);

Unlock

通常WaitForSingleObject與ReleaseMutex會用再同一個function內，一個放開頭，一個放結尾。
