调用CreateMutex创建一个有名的互斥器对象

void NameMutexExample (void) {

NULL, //No security descriptor

FALSE, //Mutex object not owned

if (NULL == hMutex) {

//Your code to deal with the error goes here.

//Here is one example of what might be done.

//Not an error -- deal with success

TEXT("Results"),MB_OK);

else

MessageBox (NULL, TEXT("CreateMutex created new mutex."),

TEXT("Result"), MB_OK);
