甚至在这个内存释放之前，namestr值就一就已经被变更，那也是为什么Purify报告一个MLK(内存渗漏)错误的原因。
Even before freeing the memory, the value of namestr has been changed, and that is why Purify reports an MLK (memory leak) error.

当您释放内存时，它就变成蓝色，这表明开始被分配后来被释放。
And when you free memory, it becomes blue, representing previously allocated but then freed memory.
许多程序都非常消耗内存—它们占用了大量的RAM，而且当其他程序需要的时候也不会释放内存空间。
Many programs are memory consumption - they occupy a large amount of ram, and when other procedures, when necessary, and will not release memory space.
对于共享内存区域，直到删除共享内存区域之后，才会释放其工作存储分页。
The working storage pages for shared memory regions are not released until the shared memory region is deleted.
结果是，即使内存在释放后立即被覆盖，并且新指向的值不同于预期值，也很难识别出新值是错误值。
The consequence is that, even if memory is overwritten immediately on freeing and the new pointed value differs from the expected one, the new value might be hard to recognize as erroneous.
避免在处理器中释放内存的最好方法是，标记或记录将要释放的对象，让程序不间断地检查是否有等待被释放的内存。
The best way to avoid freeing memory in a handler is to flag or record the objects to be freed and have the program check from time to time whether anything is waiting to be freed.
AIX分页替换守护进程一次扫描内存的一个分页，找出要回收的分页以释放内存。
The AIX page replacement daemons scan memory a page at a time to find pages to evict in order to free up memory.
任何对这个内存的访问从此以后都将是错误，因为这个内存由namestr指向的内存已经释放。
Any access to this memory thereafter should be an error, because the memory pointed to by namestr has been freed.
这个方法foo调用程序strdup，它分配内存，使用这个内存，然后释放它。
The method foo calls method strdup , which allocates memory, USES that memory, and then frees it.
这个方法main分配内存，调用foo，使用分配的内存，然后释放它并退出。
The method main allocates memory, calls foo , USES the allocated memory, and then frees it and exits.
如果应用程序的一个线程分配内存，而其他线程释放内存，那么poolallocation实际上是无效的。
Pool allocation does not work effectively if one thread of the application allocates memory and other thread frees the memory.
用特殊的系统调用(即对UNIX内核的请求)分配和释放内存并设置权限；通过一般的读写操作读写内存段中的数据。
Special system calls, or requests to the UNIX kernel, allocate and free the memory and set permissions; common read and write operations put and get data from the region.
实际上，内核本身的大部分都驻留在虚拟内存中，这样可以帮助释放内存段以供其他进程使用。
In fact, most of the kernel itself resides in virtual memory, which helps free up segments for other processes.
