On most systems, malloc and free are not reentrant, because they use a static data structure that records which memory blocks are free.
在大部分系统中，malloc和free都不是可重入的，因为它们使用静态数据结构来记录哪些内存块是空闲的。
Have a corresponding free to every malloc.
每个malloc都要有一个对应的free。
Validate_ptrs If a pointer that was previously not allocated by malloc is passed to the free call, an error message is thrown and the program is aborted.
validate_ptrs如果向free调用传递的指针并不是以前由malloc分配的，那么将会引发一个错误消息，而该程序将被中止。
Because the basic data structures in the allocator permit coalescing at any time, in any of malloc, free, or realloc, corresponding caching heuristics are easy to apply.
因为分配器中的基本数据结构允许在malloc,free或realloc的任何一个中任意时刻进行合并，相应的高速缓冲探索都很容易应用。
If the user needs to track malloc and free calls in a particular user function, the malloc.d script can be modified as shown below.
如果用户需要跟踪某个用户函数中的malloc和free调用，那么可以按以下方式修改malloc . d脚本。
For example, a memory chunk allocated with malloc in Module 3 can be freed in Module 2 with free. It is because both malloc and free calls will end up in the same instance of CRT.
例如，模块3使用malloc所分配的一段内存空间可以由模块2释放，因为对malloc和free的调用都是由同一个CRT对象实现的。
The malloc , free and realloc routines should be as fast as possible in the average case.
malloc free和realloc例程在平均情况下应该尽可能的快。
That is, if you write beyond an array's end, it won't be noticed until the next malloc or free call.
也就是说，如果你向一个数据的尾部之后写数据，程序不会注意到，直到下个malloc或者free调用。
