printf("thread 1 exit code %ld\n",(long)tret);
err=pthread_join(tid2,&tret);
printf("thread 2 exit code %ld\n",(long)tret);
return 0;
}
提示错误如下:simplepush_pop.c: In function ‘thr_fn2’:
simplepush_pop.c:32:1: error: expected ‘while’ before ‘int’
int main(void)
^
simplepush_pop.c:49:2: error: expected declaration or statement at end of input
} 此处是main函数最后的右边大括弧
^
simplepush_pop.c:49:2: error: expected declaration or statement at end of input
