The static storage-class specifiers, static and extern, can be applied to objects and functions. Table 6.1 shows where the keywords static and extern can and cannot be used.Table 6.1 Use of static and externExpand table ConstructCan static be Used?Can extern be Used? Function declarations ...
Using thestatickeyword on a local variable changes its duration from automatic duration to static duration. This means the variable is now created at the start of the program, and destroyed at the end of the program (just like a global variable). As a result, the static variable will retain...
stat_fn.c:12: warning: `foo2' was declared `extern' and later `static'And then I thought, maybe changing the declaration for foo2()withing foo1() to 'static void foo2(void);' would silence thewarning. Then the new file would look like this:/** stat_fn1.c **/#include void ...

auto,static,extern tip 在理解这三者之间的作用和区别之前,需要先来理解一个叫做存储类别标识 (Storage-class specifiers)的东西。 存储类别标识: 指定对象或函数的存储周期(Storage duratong)和连接(linkage)方式。 存储分类标识包含以下几个标识: auto -自动存储周期和我连接(automatic duration and no linkage)...
