做这样的事情是否合法：
#include" x.c"在其他源文件中？
这是个好主意吗？

那没关系，伊戈尔。将多个
thourtheth合并到一个程序中的第一种方法是将它们分别编译，然后将
链接在一起。对于ecthample来说，如果你是GNU编译器的那些东西，那么b b b b b b b b b b b b b b b b b b b b ,,,,,,,,,,,,,,,,,,,,,, br />
gcc -W -Wall -ansi -pedantic -c -o xo xc
gcc -W -Wall -ansi -pedantic -c -o yo yc
gcc -W -Wall -ansi -pedantic -c -o zo zc
gcc -W -Wall -ansi -pedantic -o foo xo yo zo
我可能会因为你冒犯你的实施情况而感到害羞吗？

That''th all right, Igor. The uthual way to incorporate multiple
thourtheth into one program ith to compile them theparately, and then
link them together. For ecthample, if you are uthing the GNU compiler
(which begth to be lithped, but I lack thuffithient thpittle), you
might do thith:
gcc -W -Wall -ansi -pedantic -c -o x.o x.c
gcc -W -Wall -ansi -pedantic -c -o y.o y.c
gcc -W -Wall -ansi -pedantic -c -o z.o z.c
gcc -W -Wall -ansi -pedantic -o foo x.o y.o z.o

去过牙医吗？ ;-)
几年前有一个项目我在其中包含了一个代码文件。
我正在为多个端口编写串行I / O驱动程序，但是使用单个
函数和指针/索引到与端口关联的数据区域
显着增加了中断处理时间。我写了一个
程序作为模板，然后为每个
端口设置了单独的包装函数，其中包括为
$ b $设置定义常量后的代码文件b端口值。对于每个驱动程序，端口是常量，因此不需要运行时间来进行索引或取消引用。 I / O端口也直接
地址。
底线是代码是在一个地方定义的，并且是
在多个地方实例化，以牺牲代码来优化速度
空间。想想看，它与
类似函数的宏用法和内联函数的情况类似，只是以不同的方式来调用它。
这是一种技术，但我只在特殊情况下使用。

Been to the dentist? ;-)
There was a project several years ago in which I included a code file.
I was writing serial I/O drivers for multiple ports, but using a single
function and pointers/indexes to the data area associated with the port
significantly increased the interrupt processing time. I wrote one
procedure as a template, then had separate wrapper functions for each
port which included the code file after setting a defined constant for
the port value. For each driver the port was constant, so no run-time
indexing or dereferencing was needed. The I/O ports were also directly
addressed.
Bottom line was that the code was defined in one place, and was
instantiated in multiple places to optimize speed at the expense of code
space. Come to think of it, that''s similar to what happens with
function-like macro usage, and inline functions, just a different way to
invoke it.
It''s a technique, though, which I use only in special circumstances.
