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 first must create the buffer, fill it, then rewind the position to the beginning so you can read from the start.
必须首先创建一个缓冲区，先填充它，然后将位置倒回起始点，这样才能从头读。
Here, reading the bytes is not enough to extract the necessary information; it returns a buffer if the string is read.
此处，读取字节还不足以提取必要的信息，如果要读取字符串，则要返回一个缓冲区。
Buffer Cache - Memory allocated for storing data blocks read from physical data files.
缓冲区缓存——为存储从物理数据文件读取的数据块而分配的内存。
You can point it at another file quite easily; it's a bit harder to, for instance, read from a buffer.
您可以非常简单地将它指向另外一个文件；从缓冲区中进行读取稍微有些困难。
The buffer address is actually a user-space buffer, so you won't be able to read it directly.
缓冲区地址实际上是一个用户空间的缓冲区，因此我们不能直接读取它。

该缓冲区缓存原本需要从磁盘读取的JMS消息数据。
The consumer of the ATQ operator can read data one row at a time from the ATQ buffer.

Further, applications that might benefit from having a file system read ahead or high buffer cache hit rates might actually see performance degradation.
而且，对于那些受益于文件系统预读功能或者较高缓冲区缓存命中率的应用程序，可能会出现性能的降低。
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。
Number of pages prefetched into the buffer pool, but never read.
预抓取到缓冲池，但从未读取的页面数量。
In a similar fashion, you can read data segments off segment by segment from an abstract buffer with the following function.
采用类似的方式，您可以使用以下函数，逐段地从抽象缓冲区读取数据段。
Now that you have the unpacked values from the binary buffer that you read, you can use the standard print commands to get the output necessary.
现在您已从读取的二进制缓冲区获得了拆包的值，那么您可以使用标准的print命令来获得必要的输出。
This command USES the klogctl system call to read the kernel ring buffer and emit it to standard output (stdout).
这个命令使用klogctl系统调用来读取内核环缓冲区，并将它转发到标准输出(stdout)。
Interestingly, Ruby 1.9.0 has the lowest CPU usage, with an implementation that uses readpartial, "no timeout for socket reads" and "pre-allocated String buffer for each read".
有趣的是，Ruby1.9.0对CPU的占有率最低，其实现采用了 readpartial：“不对socket读取设置超时”，同时“提前为每次读取分配字符串缓存”。
When MySQL must perform a sort, it allocates a sort buffer to store the rows as they're read from disk.
当MySQL必须要进行排序时，就会在从磁盘上读取数据时分配一个排序缓冲区来存放这些数据行。
The transferTo() method causes the file contents to be copied into a read buffer by the DMA engine.
transferTo()方法引发DMA引擎将文件内容拷贝到一个读取缓冲区。
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。
For example, assume that Member 1 in Figure 1 wants to read a data page that isn't in its local buffer pool.
例如，假设图1中Member 1要读取不在它本地缓冲池中的数据页。
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。
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。
Step two: data is copied from the kernel buffer into the user buffer, and the read system call returns. The return from the call caused a context switch from kernel back to user mode.
步骤二：数据从内核空间缓冲区复制到用户空间缓冲区，之后系统调用read返回，这导致了从内核空间向用户空间的上下文切换。
In a buffer wrap condition, the first read returns only the keyword BUF_WRAP.
如果出现缓冲区回绕，第一个read只返回关键字BUF _WRAP。
The requested amount of data is copied from the read buffer into the user buffer, and the read call returns.
所需的数据被从读取缓冲区拷贝到用户缓冲区，read调用返回。
Step two: data is copied from the kernel buffer into the user buffer, and the read system call returns.
所需的数据被从读取缓冲区拷贝到用户缓冲区，read()调用返回。
