调用CreateMutex创建一个有名的互斥器对象

void NameMutexExample (void) {

 HANDLE hMutex;

TCHAR szMsg[100];

hMutex = CreateMutex (

                               NULL,                   //No security descriptor

                               FALSE,                 //Mutex object not owned

                                TEXT("NameOfMutexObject"));         //Object name

  if (NULL == hMutex) {

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

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

    wsprintf (szMsg, TEXT("CreateMutex error: %d."), GetLastError ());

    MessageBox (NULL, szMsg, TEXT("Error"), MB_OK);

  else {

  //Not an error -- deal with success

  if ( ERROR_ALREDAY_EXISTS == GetLastError ())

      MessageBox (NULL, TEXT("CreateMutex opened existing mutex."),

                               TEXT("Results"),MB_OK);

  else

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

                             TEXT("Result"), MB_OK);
