When another user requires access to the file, their security credentials are verified before being granted access to the data even though the file data is already in memory and in clear format.
当另一个用户需要访问该文件时，在授予对数据的访问权限之前，将验证其安全凭据，既使这些文件数据已经以明文格式存在于内存中。
Linux uses the shmget/mmap function to access files by directly incorporating file data into memory.
Linux使用shmget/mmap函数通过直接将文件数据 合并入内存来访问文件。
The first copy (see Figure 1) is performed by the direct memory access (DMA) engine, which reads file contents from the disk and stores them into a kernel address space buffer.
直接内存存取(direct memory access,DMA)引擎执行了第一次拷贝(参见图1)，它从磁盘中读取文件内容，然后将它们存储到一个内核地址空间缓存区中。
The access to the file USES the same syntax as the previous example, remember that if you close the memory mapped file this will be non accessible, this issue catches many developer.
如何访问文件就跟前述的示例一样了。千万记住，如果你关闭了内存映射文件，那么它就不能访问了。
All threads within a single process have access to the same process components, such as file descriptors and memory.
在一个单个进程内所有的线程都有权使用这个同一个进程构成，像文件描述符和内存。
Threads, on the other hand, automatically have access to the same memory address space and file descriptors.
另一方面，线程可以自动的访问相同的内存地址和文件描述符。
I try to open a H2 database file with the H2 console and always get the "out of memory" error message and maybe Microsoft Access can help now.
我尝试与H2 H2控制台打开数据库文件，总是得到“内存不足”的错误信息，也许可以帮助我们获得微软。
