互斥锁，锁不住

[toadzw]

#ifdef WIN32

#include <windows.h>
HANDLE mutex_key_mem ;


void initLock(com_lock *mylock){
if(mylock == NULL){
printf("init lock---------------------------------\n");
mylock= CreateMutex(NULL, FALSE, NULL);
}
else{
printf("lock has exsit \n");
}
return ;
}

int lockMutex(com_lock *mylock){
if(mylock == NULL){
printf("please init lock first\n");
return -1 ;
}else{
printf("lock ...");
WaitForSingleObject(mylock, INFINITE);
printf("lock ...\n");
Sleep(1000);
printf("locking\n");
return 0;
}

}

int unlockMutex( com_lock *mylock){
if(mylock == NULL){
printf("please init lock first before unlock\n");
return -1 ;
}else{
printf("unlock ...");
ReleaseMutex(mylock);
return 0 ;
}

}
这个锁怎么锁不住啊，还是跑进去了
