typedefvoidfunction();voidhello(){printf("Hello\n");}voidgoodbye(){printf("Goodbye\n");}intmain(){ function * pf = hello; pf();// prints "Hello"pf = goodbye; pg();// prints "Goodbye"} Run Code Online (Sandbox Code Playgroud) 在这种情况下,它允许您编写一个函数来处理TCL输出的某些方面,并告诉TCL使用该函数.
This provides a powerful and generic facility that can be customized by clients to create type-safe shared pointers to any object, such as std::shared_ptr<MyCustomClass>. Templates therefore offer an excellent way for you to write extensible code that can be applied to many different types, ...

R (*func_)(Arg); 你也可以用一个 typedef 来让它好读一些。 Literature For instance, in each line after the first line of: typedef int (*funcptr)(double); // pointer to function taking a double returning int funcptr x = (funcptr) NULL; // C or C++ funcptr y = funcptr(NULL...
