Messages are collections of parameters used as profiles in determining the input and output values for a function call.
消息是参数的集合，这些参数用作确定函数调用的输入和输出值的配置文件。
However, to make an RFC call from an application, you need to specify the name of the BAPI and the details of its interface including the import parameters (input) and the export parameters (output).
不过，若要从应用程序执行RFC调用，您需要指定BAPI的名称及其接口的详细信息，其中包含导入参数(输入)和导出参数(输出)。
Modify the generated client to declare proper input and output variables, and pass these as parameters for the Web service method call.
修改生成的客户机以声明合适的输入和输出变量，并将这些作为参数传递给Web服务方法调用。
Now assume that Component1 needs to call method2 and method3 with the same input data to get different output data.
现在假设Component1需要用相同的输入数据调用method2和method3来获取不同的输出数据。
This is important in Python programs because file input and output are, by default, buffered; data isn't written as soon as you call a print statement but is instead written in chunks.
在Python程序中这很重要，因为在默认情况下，文件输入和输出是缓冲的；在调用print语句时，数据实际未被写入；相反，数据是成批写入的。
This feature is implemented using the popen system call, which allows one process to open a pipe to another process, either for output or input. In this case we open a pipe to the command.
这一特性是用popen系统调用实现的，该系统调用允许一个进程打开到另一个进程的管道，将管道用于输出或输入。
The role of the main function (see Listing 7) then becomes solely instantiating the proper input and output formats, culminating in the readFeaturesInto function call.
主函数的作用（参见清单7）就继而变成了单纯地实例化恰当的输入和输出格式，并最后以readFeaturesInto 函数调用告终。
This solution would call for multiple sound output devices (on many systems, programs such as Festival and MPlayer can direct the output to a specific device) or coordinated input to one device.
这种解决方案需要调用多个输出设备(在许多系统中，Festival和MPlayer等程序可以将输出发送到特定的设备)或者在一个设备上协调输入。
A business object (bo) is used to represent a BAPI call and it contains both the input and output parameters, as shown in Figure 4.
使用业务对象(BO)代表BAPI调用，BO包含输入和输出参数，见图4。
While we add an appropriate topology to the space, the input-output map will become a topological dynamic system, and we call it CNN symbol dynamic system.
置以合适的拓扑，则这个空间及其输入一输出映射就构成了一个拓扑动力系统，称这个动力系统为CNN符号动力系统。
All we need to do is call the Merge method and specify the input files and output file.
所有我们需要做的就是调用合并方法，并指定输入文件和输出文件。
The call and input of the data together with the output message calibration can be realized in the form of men-machine interaction.
可通过人机交互方式实现选针循环数据的调用或输入，以及产量信息的标定。
This system call allows your program to check for input, output, or error conditions on one or more file descriptors.
这个系统调用允许你的程序从一个或多个文件描述符获取输入输出或者错误信息。
This system call allows your program to check for input, output, or error conditions on one or more file descriptors.
这个系统调用允许你的程序从一个或多个文件描述符获取输入输出或者错误信息。
