c++ - pthread_cleanup_pop error on Windows- make it compilable -

code:

    void clean(void *message)     {      cout<<"exiting "<<(char*)message<<endl;     }     void *func2(void* arg)     {        char *message = "func2";        pthread_cleanup_push(clean,(void*)message);        int status;        int count=0;           pthread_setcancelstate(pthread_cancel_enable,&status);        for(;;){           if(count%3467==0)           {               sleep(3);               pthread_testcancel();           }           else if(count%67==0)           {               cout<<"func 2 running"<<endl;           }           else           {}           count++;        }         pthread_cleanup_pop(0);//error pointing here     } 

when try compile , getting error

cancel.cpp:45:5: error: second operand conditional operator of type 'v oid', third operand neither throw-expression nor of type 'void'      pthread_cleanup_pop(cleanup_pop_arg); 

i not able find what's problem code. compiled g++ file.cpp -pthread , windows 8, cygwin 64.

how make code compile successfully?

edit:

after preprocessing how look.

void *func2(void* arg) {     char *message = "func2";    { const _pthread_cleanup _pthread_cup = {(clean), ((void*)message), *pthread_getclean()}; __sync_synchronize(); *pthread_getclean() = (_pthread_cleanup *) &_pthread_cup; __sync_synchronize();    int status;    int count=0;    pthread_setcancelstate(0x01,&status);    for(;;){       if(count%3467==0)       {           sleep(3);           pthread_testcancel();       }       else if(count%67==0)       {           cout<<"func 2 running"<<endl;       }       else       {}       count++;    }     (*pthread_getclean() = _pthread_cup.next, (cleanup_pop_arg?_pthread_cup.func((pthread_once_t *)_pthread_cup.arg):0));};  }
