英汉例句

• the more dynamic a program is, the more memory management becomes an issue, and the more important your choice of memory allocator becomes.

  程序的动态性越强，内存管理就越重要，您的内存分配程序的选择也就更重要。

• note that the version of my allocator they describe is not the most current one however.

  （注意，他们描述的我的分配器的版本并不是最新的）。

• since it operates on the system break (a global variable), it cannot coexist with any other allocator or with mmap.

  由于它对系统中断点（一个全局变量）进行操作，所以它不能与其他分配程序或者mmap一起使用。

• on unix systems, you can now use your allocator in place of your system malloc() by doing this

  在unix系统中，现在您可以用您的分配程序来取代系统的malloc()，做法如下

• in c++, you can implement your own allocator on a per-class or per-template basis by overloading operator new().

  在 c++ 中，通过重载operatornew()，您可以以每个类或者每个模板为单位实现自己的分配程序。

• bsd malloc: bsd malloc, the implementation that was distributed with 4.2 bsd and is included with freebsd, is an allocator that allocates objects from pools of objects of pre-determined sizes.

  bsdmalloc：bsdmalloc是随4.2bsd发行的实现，包含在freebsd 之中，这个分配程序可以从预先确实大小的对象构成的池中分配对象。

• the pool interface needs to know the size of each individual element and not the type, because it「s a malloc-style allocator and doesn」t call constructors.

  pool接口需要知道每个单独的元素而不是类型的大小，因为它是一个malloc风格的分配程序，不会调用构造函数。

• however, over the years, the allocator has evolved to make trade-offs that the majority of users find to be acceptable.

  尽管如此，这些年来，这个分配器已经进化到做了一些大部分用户都可以接受的取舍。

• such a static allocator might lazily create each type of event the first time it is needed and subsequently return the same instance each time, updated with the new information.

  在第一次需要它的时候，这样一个静态的分配器可能会创建事件的每个类型，以后每次只返回由新的信息更新过的相同实例。

• there remains one kind of caching that is highly desirable in some applications but not implemented in this allocator -- lookasides for very small chunks.

  在一些程序中仍然时分需要有一种高速缓沖，但是它并没有在该分配器中被实现--对很小的块进行后备。

• in fact, if you do this, you can use the same ld_preload trick that we used for our simple allocator to enable garbage collection in almost any program on your system.

  实际上，如果这样做，您就可以使用与我们在示例分配程序中所使用的相同的 ld_preload技巧，在系统上的几乎任何程序中启用垃圾收集。

• however, if you aren「t familiar with allocator design, custom allocators can often create more problems than they solve.

  不过，如果不熟悉分配程序的设计，那么定制分配程序通常会带来比它们解决的问题更多的问题。

• to build your malloc-compatible allocator (actually, we」re missing some functions like realloc(), but malloc() and free() are the main ones), run the following command

  运行下面的命令来构建malloc兼容的分配程序（实际上，我们忽略了 realloc() 等一些函数，不过，malloc()和free()才是最主要的函数）

• doug lea's allocator has a basic structure much like our version, but it incorporates indexes to make searching faster and has the ability to combine multiple unused chunks into one large chunk.

  douglea的分配程序有着与我们的版本非常类似的基本结构，但是它加入了索引，这使得搜索速度更快，并且可以将多个没有被使用的块组合为一个大的块。

• an allocator should be plug-compatible with others; in particular it should obey ansi/posix conventions.

  一个分配器应该可以和其他程序插件式兼容；特别是它应该遵守ansi/posix惯例。

• i wrote the first version of the allocator after writing some c++ programs that almost exclusively relied on allocating dynamic memory.

  在写了一些几乎严重依赖于动态分配内存的c++程序之后，我编写了这个分配器的第一个版本。

• implementing a simple allocator

  实现一个简单的分配程序

• if locality were the only goal, an allocator might always allocate each successive chunk as close to the previous one as possible.

  如果局部化是唯一的目标，分配器可能总是尽可能接近的分配每个连续的块。

• not only does our memory manager have shortcomings, there are many shortcomings of malloc()-based memory management that remain no matter which allocator you use.

  不只是我们的内存管理器有缺点，基于malloc()的内存管理器仍然也有很多缺点，不管您使用的是哪个分配程序。

• at present, the maximum pool size per process for this allocator is limited to 512mb.

  目前，对于这个分配器，每个进程的最大池大小限制为512mb。

• vfs inodes are allocated using the slab allocator (from the inode_cache; see resources for a link to more information on the slab allocator).

  vfsinode使用slab分配器进行分配（来自 inode_cache； 参考资料 部分提供一个介绍slab分配器的链接）。

• previous versions of the allocator used a few search-ordering heuristics that made adequate guesses about caching, although with occasionally bad worst-case results.

  以前版本的分配器使用一些搜索-排序尝试对高速缓沖进行足够的猜测，尽管偶然会遇到最坏情况。

• it frees every memory block you created earlier and invalidates all the pointers returned from the allocator routines.

  该方法释放您先前创建的内存块，并使得从分配程序例程返回的所有指针失效。
