我正在开发一个应用程序，我每隔1秒调用一个函数。但该计划陷入僵局，我无法找到根本原因。这是我的示例代码
＆＃xA;＆＃xA; #include＆lt; stdio.h＆gt;＆＃xA; #include＆lt; stdlib.h＆gt;＆＃xA; #include＆lt; time。 h＆gt;＆＃xA; #include＆lt; pthread.h＆gt;＆＃xA; #include＆lt; unistd.h＆gt;＆＃xA; #include＆lt; signal.h＆gt;＆＃xA;＆＃xA; pthread_mutex_t loc;＆＃xA; pthread_t StartProcessThread;＆＃xA; void fun（int t）;＆＃xA; void * vStartProcess（void *）;＆＃xA;＆＃xA; int main（）＆＃xA; {＆＃xA; bool t = true;＆＃xA; struct itimerspec TimerSpec;＆＃xA; struct sigaction sa;＆＃xA;＆＃xA; timer_t timerId;＆＃xA;＆＃xA; int nResult = pthread_mutex_init（＆amp; loc，NULL）;＆＃xA;如果（nResult！= 0）＆＃XA; {＆＃XA; perror（“无法初始化ReportedTrackListLock互斥锁\ n”）;＆＃xA;出口（EXIT_FAILURE）;＆＃XA; }＆＃XA;＆＃XA; nResult =在pthread_create（安培; StartProcessThread，NULL，vStartProcess，NULL）;＆＃XA; if（nResult！= 0）//检查是否成功创建了线程，如果没有退出＆＃xA; application＆＃xA; {＆＃XA; printf（“创建StartProcessThread线程时出错...退出应用程序\ n”）;＆＃xA;出口（EXIT_FAILURE）;＆＃XA; }＆＃XA;＆＃XA; TimerSpec.it_interval.tv_sec = 1;＆＃XA; TimerSpec.it_interval.tv_nsec = 0;＆＃XA; TimerSpec.it_value.tv_sec = 1;＆＃XA; TimerSpec.it_value.tv_nsec = 0;＆＃XA;＆＃XA; sa.sa_handler =安培;乐趣;＆＃XA; sa.sa_flags = 0;＆＃XA; sigemptyset（安培; sa.sa_mask）;＆＃XA;＆＃XA;的sigaction（SIGALRM，＆安培; SA，NULL）;＆＃XA;＆＃XA; long a = timer_create（CLOCK_REALTIME，NULL，＆amp; timerId）;＆＃xA;如果（一个！= 0）＆＃XA; {＆＃XA; printf（“创建计时器时出错...退出应用程序\ n”）;＆＃xA;出口（EXIT_FAILURE）;＆＃XA; }＆＃XA; a = timer_settime（timerId，0，（const itimerspec *）＆amp; TimerSpec，NULL）;＆＃xA;如果（一个！= 0）＆＃XA; {＆＃XA; printf（“设置定时器时出错...退出应用程序\ n”）;＆＃xA;出口（EXIT_FAILURE）;＆＃XA; }＆＃XA; pthread_join（StartProcessThread，NULL）;＆＃xA;}＆＃xA;＆＃xA;＆＃xA; void fun（int t）＆＃xA; {＆＃xA; printf（“来到这里\ n”）;＆＃xA;的pthread_mutex_lock（安培; LOC）;＆＃XA;睡眠（2）;＆＃XA;调用pthread_mutex_unlock（安培; LOC）;＆＃XA; printf（“来到这里1 \ n”）;＆＃xA;}＆＃xA;＆＃xA; void * vStartProcess（void *）＆＃xA; {＆＃xA; printf（“thread created \ n”）;＆ #xA; bool t = true;＆＃xA;而（T）＆＃XA; {＆＃XA;的pthread_mutex_lock（安培; LOC）;＆＃XA;睡眠（1）;＆＃XA;调用pthread_mutex_unlock（安培; LOC）;＆＃XA; }＆＃XA;返回NULL;＆＃xA;}＆＃xA; ＆＃xA;＆＃xA; 有人请帮我解决这个问题
