Buffer Write: Number of pages modified and sent back to the buffer pool.
Buffer Write：修改并发送回缓冲区池的页面数量。
You could even just use a single pointer and write data back into the buffer you got it from, although this might be a nuisance to program for on the other end.
您甚至只需要使用一个指针并将数据写回到读取数据所使用的缓冲区中即可，不过这对于另外一端的编程来说可能有些麻烦。
Use the database system monitor to help you tune this configuration parameter using information from the snapshot data (or event monitor) about write activity from a buffer pool.
使用数据库系统监视器，利用有关从缓冲池进行写操作的快照数据(或事件监视器)信息来帮助您调优该配置参数。
Thus, the read operations compete with log writing and the write operation for data pages from the buffer pool.
因而，读操作与日志写和缓冲池中的数据页的写操作之间存在竞争。
You can write trace data to a file continuously as an extension to the in-storage trace, but instead of one buffer per thread, at least two buffers per thread are allocated.
可以连续地将跟踪数据写到文件中，作为存储内跟踪的扩展；但是在这种情况下不是为每个线程分配一个缓冲区，而是至少分配两个。
After writing the first log entry, shown in blue, when the process tries to write the second one, shown in red, the buffer doesn't have enough space left.
在写入了第一个日志条目(用蓝色表示)之后，当该进程尝试写入第二个条目(用红色表示)时，该缓冲区中已经没有足够的剩余空间。
The intermediate buffer on the write side allows the write to complete asynchronously.
在写入方面的中间缓冲区则可以让写入过程异步完成。
Page cleaners, on the other hand, write changed pages from the buffer pool to disk before the space in the buffer pool is required by a database agent.
另一方面，数据库代理需要缓冲池中的空间之前，页面清洗器将已修改的页面从缓冲池写入磁盘。
These page cleaners write changed pages from the buffer pool to disk before the space in the buffer pool is required by a database agent.
在数据库代理程序需要缓冲池中的空间之前，这些页清除程序将缓冲池中已更改的页写到磁盘。
The verbose trace will display data from the parameters of system calls (-x all) and the contents of the buffer for both Read (-r all) and Write (-w all) calls.
详细的跟踪会显示来自系统调用参数的数据(- x all)以及Read (- r all)和Write (- w all)调用的缓冲区的内容。
Because the buffer that I'll write to (page) is already in kernel space, I can manipulate it directly and use sprintf to write the next fortune.
由于我们刚才写入数据的缓冲区(page)已经在内核空间中了，因此可以直接对其进行操作，并使用sprintf来写入下一个fortune。
You'd have to write a handler to build what amounts to an in-memory buffer to keep up with what's already been read; then you'd need some code to read ahead as well.
所以，必须要编写一个相当于内存缓冲器的处理程序来记录已读的内容，也同时需要编写一些代码进行提前读。
Linux, under normal circumstances, USES a system file cache to buffer, read, and write requests from disk.
在一般情况下，Linux使用一个文件系统缓存为磁盘请求进行缓冲和读写。
Memcached USES a per-connection buffer to read and write data out over the network.
memcached为每个链接使用单独的缓存进行数据的读写。
First, we create need a buffer to write to for the sprintf call using the malloc function.
首先，我们在使用malloc函数中的sprintf调用时需要创建一个缓冲器(buffer)。
The log buffer acts as a staging area in memory to hold log records instead of having the DB2 UDB engine write each log record directly to disk.
日志缓冲区作为内存中的分级区域（staging area）来保存日志记录，而不是让DB2UDB引擎直接将每条日志记录写入磁盘中。
There might not be enough disk space to complete the file write operation, or allocating the buffer could fail if not enough memory is available.
可能没有足够的磁盘空间来完成该文件的写操作，或者由于没有足够的内存可用，分配缓冲区可能失败。
Only a small buffer is needed to read or write data.
它只需要使用一个很小的缓冲区来读写数据。
For example, read and write requests to the underlying device drivers migrate through the buffer cache.
例如，对底层设备驱动程序的读写请求会通过缓冲区缓存来传递。
Each thread can read and write only to its own slot, rather than to the complete buffer.
每个线程只能够读写它自己的槽位，而不是整个缓冲区。
In Listing 1, I set up libtiff and create a simple buffer that contains an image I can then write out to disk.
在清单1中，我设置了libtiff并创建一个简单的缓冲区，使之包含我稍后可以写到磁盘上的图像。
In doing so, it triggers a series of buffer overflows allowing it to write various pieces of data and code to the stack.
这样做，它触发出一系列的缓存溢出，以允许自己向栈写入许多数据和代码。
So the buffer is used to accumulate more characters and write them all in one write operation.
所以缓冲区用于积累更多的人物和写在一个写操作。
Why do most systems take a significant amount of time to write characters to an output device? What is this buffer and why do we require it? Why do we require flushing buffers?
为什么大多数系统需要大量的时间来写字符输出设备?这是什么缓冲，我们为什么需要它?为什么我们需要冲洗缓冲?。
A buffer is a queue of characters that are ready to write.
的字符缓冲区队列已经准备好写。
A buffer is a queue of characters that are ready to write.
的字符缓冲区队列已经准备好写。
