Try it Yourself » In C99 mode, extern inline always emits a function, but like in C++, it will be shared among translation units. Thus, the same function can be defined extern inline in different translation units. This matches the traditional behavior of Unix C compilers for multiple non-extern definitions of uninitialized global variables. Restrictions Seterra är ett gratis geografiprogram som med hjälp av blindkartor lär dig städer och länder i hela världen. extern int inc (int *a); inline int inc (int *a) { return (*a)++; } In both of these common cases, the program behaves the same as if you had not used the inline keyword, except for its speed. When a function is both inline and static , if all calls to the function are integrated into the caller, and the function’s address is never used, then the function’s own assembler code is never referenced. extern inline.

2018-11-08 Hi! I am confused with the extern, stratic and inline statements. I have function declared in the header as this public class MyClass { static inline float Add(float a, float b); }; and in the .cpp file the definition inline float Myclass::Add(float a, float b) { return a+b; } but the compiler do · mastermemorex wrote: Hi! I am confused with the extern _GL_EXTERN_INLINE is a portable alternative to 'extern inline'. _GL_INLINE_HEADER_BEGIN contains useful stuff to put: in an include file, before uses of _GL_INLINE. It suppresses GCC's bogus "no previous prototype for 'FOO'" diagnostic, when FOO is an inline function in the header; see 2018-12-03 If anyone uses extern inline in the way that it is intended, i.e. provide an inline function in a header and an out-of-line version of the same function in some C file, that breaks. It would be pointless to use extern inline this way now, since we define inline to mean always_inline in the kernel, but gcc will give you a 2020-08-06 Köp Externa hårddiskar online på kjell.com.

This combination of inline and extern has almost the effect of a macro. The way to use it is to put a function definition in a header file with these keywords, and put another copy of the definition (lacking inline and extern) in a library file.

That said, it looks like it's a behavior that they document; their documentation says "In C++, this attribute does not depend on extern in any way, but it still requires the inline keyword to enable its special behavior." and that matches their observed behavior. And they behave this way even for functions in extern "C" blocks.

what can the compiler do where This combination of inline and extern has almost the effect of a macro. The way to use it is to put a function definition in a header file with these keywords, and put another copy of the definition (lacking inline and extern) in a library file. The definition in the header file will cause most calls to the function to be inlined. static inline and static extern are both combinations of the two terms.

extern inline void. serial_init (void) { } When an inline function is not static, then the compiler must assume that there may be calls from other source files; since a global symbol can be defined only once in any program, the function must not be defined in the other source files, so the calls therein cannot be integrated.

What will be the output of the following C code? #include extern inline int min(int a, int b) { return a < b ? a : b; } main() { int m; m=min(3,-5); printf("%d" extern void my_func(void);. and defined in my_file.c. Code: Select all inline void my_func(void) { /* DO SOMETHING */ }.

extern 对于非函数的对象是有用的,因为对象声明时会带来内存的分配,而用 extern 就表示该对象已经声明过了,不用再分配内存.

The extern keyword may be applied to a global variable, function, or template declaration. It specifies that the symbol has external linkage. For background information on linkage and why the use of global variables is discouraged, see Translation units and linkage. The extern keyword has four meanings depending on the context:

The extern keyword has four meanings depending on the context: Inline style (inside an HTML element) External and internal style sheets (in the head section) Browser default; So, an inline style has the highest priority, and will override external and internal styles and browser defaults.
