c - Splint 中的 "Fresh Storage"是什么？

Question

我在 Splint 文档中搜索了“fresh storage”，发现有提及，但没有正式定义。其他修饰符，如 null 或 only，我理解并正在使用。我只是不确定新鲜存储是什么。

情况是这样的:

void output_system_information(unsigned int frequency, unsigned int duration) { 

   unsigned int intervals = duration/frequency;                                  

   /* here I allocate some storage */                                                                              
   System * my_system = malloc(sizeof(System));                                  

   SystemInfo* current, * total;                                                 

   if (my_system == NULL) {                                                      
     fprintf(stderr, "%s\n", "Aborting: failed malloc in output_system_informatioin");
     exit(EXIT_FAILURE);                                                         
   }                                                                             

   /* and here I initialize is in that function */                                              
   init_system(my_system);      
   total = tally_system_info(frequency, duration, my_system);                    
   current = my_system->get_system_info();                                       

   /* Here I've removed a ton of print-line statements so that you don't have to see them */

   /* then the members and the struct get freed in this here dtor */
   delete_system(my_system);                                                     
   free(current);                                                                
   free(total);                                                                  

   return;                                                                       
}            

这是一项家庭作业，但这个问题不一定与家庭作业直接相关。这是一个夹板问题。

术语新鲜存储指的是刚刚分配给您的程序的内存缓冲区。

警告 “Fresh storage not released” 只是 “Only storage not released” 的一个特例，当缓冲区由同一函数分配时失败释放它。
