例如，必须用参数形式包括进类型信息，必须用函数形式返回值和所有变量的类型。
For example, you must include type information with arguments, return values with functions, and types for all variables.
c语言没有包含一种内置的功能来处理异常，因此默认情况下，如果您不处理函数的返回值，它就会将其忽略。
C doesn't include a built-in capability to handle exceptions, so by default it ignores any function returns if you don't do anything with them.
如果启用了模式感知（参阅后面的 模式感知），这些类型的值可以来自转换的输入文档或者函数的返回值。

函数和返回值。
这里的udr一词通常用来指代返回值的函数。
Here the term UDR is used generically to refer to functions that return a value.
您也可以将函数的返回值和test或while之类的命令结合使用来控制分支和循环。
You might also use return values from functions with command such as test or while to control branching or looping.
所以increment函数不带入参，也不返回值，它也没做什么。
So this function increment takes nothing, returns nothing, and yet it does something.
函数还可返回值(更为正式的说法是：对象)，包括像tuple这样的python容器。
The function can also return a value (or, more formally, an object), including a Python container like a tuple.
清单2.适当处理readapi函数的返回值。
Listing 2. Proper handling of the read API function return value.
当您调用带有包含数字 1 到 5的list或tuple 的函数时，返回值会显示在屏幕上。
The returned value is displayed to the screen when you call the function with a list or tuple holding the numbers 1-5 inclusive.
filetype(name )函数的返回值 —常量FILE或常量DIR — 将文件系统中的每一项整理到相应的slot 中。
The return value of the function filetype( name )—either the constant FILE or the constant DIR—collates each item in the file system into its appropriate slot.
但是为了一致性，每次调用分派器都会返回一个从控制传播内容的所有函数中返回的返回值列表。
For uniformity, however, every call to a dispatcher returns a list of return values from all functions that control what was propagated to.
你可以可以为变量指明数据类型，输入参数，来自函数的返回值，用户自定义函数以及模板。
You are also able to specify data types for variables, input parameters, return values from functions, user-defined functions and templates.
通过在出口点应用跟踪钩子并指定函数原型，可以探测函数的退出/返回值。
Tracing of exit/return value of a function is possible by applying trace hook at exit point and specifying function prototype.
该构造函数的返回值是一个节点，可以使用与上面示例中相同的方式将其添加到树中。
The return value of this constructor is a node that you can add to the tree in the same way as the nodes in the above example.
当服务器从客户端收到请求后，服务器执行本地函数，并将该函数的返回值返回给客户端。
