The others ( __LINE__ and __FILE__) are just fine. This name is the unadorned name of the function. They are functionally equivalent to the predefined identifier, __func__. I believe, you could just #define __func__ __FUNCTION__ and get pretty much the C99 behavior. Vulkan Memory Allocator 2.1.0 (28 Aug 2018) str_view - null-termination-aware string-view class for C++ (19 Aug 2018) July 2018 add a note. Show activity on this post. The stored callable object is called the target of std::function. Some old versions of C and C++ supports __func__. Tue 11 Sep 2018. 前言. Note: in the scope of every function body, there is a special function-local predefined variable named __func__, defined as a static character array holding the name of the function in implementation-defined format. Change a few printk(KERN_* to equivelent pr_* form and use __func__ instead From C99 §6.4.2.2/1:. __FUNCTION__ 特性最初是为C语言设计的，然而，C++程序员也会经常需要有关他们函数的额外信息，在Visual Studio 2005中，还支持另外两种非标准的扩展特性：__FUNCDNAME__ 与 __FUNCSIG__ ，其分别转译为一个函数的修饰名与签名。 Follow. 191. > This seems to stem from the recent __FUNCTION__ vs. __func__ > change in kernel.h and the SX driver's use of __FUNCTION__ in the > following construct > > #define func_enter() sx_dprintk (SX_DEBUG_FLOW, "sx: enter " __FUNCTION__ "\n") > The parenthesised (__func__) is there to force you to not try to perform this string pasting. Sign In Sign Up Sign In Sign Up Manage this list I believe, you could just #define __func__ __FUNCTION__ and get pretty much the C99 behavior. The __func__ is really useful, but.. Identifiers that represent statements or expressions are called macros. C macros __LINE__, __FILE__ and __func__ It is possible for a C program to print the currently executing line of source code, the file of the source code, and the name of the current function. __FILE__ [predefined macro] 전처리기의 의해서 현재의 소스 파일명의 문자열 상수(string literal)로 치환된다. View post. Some macros are defined only for specific build environments or compiler options. Then the code is C99 correct and the preprocessor conditional can be removed without harm in the future. Here, we will see one of these predefined identifiers of C programming language which is __func__. Unlike function declaration, function definitions are allowed at file scope only (there are no nested functions). or I think so. RMS reimplemented it as __FUNCTION__, and added it the the standard gcc . In this preprocessor documentation, only the term "macro" is used. For the compilers . __FUNCTION__ is gcc-specific, use __func__ Long lines have been kept where they exist, some small spacing changes have been done. Neither of them is a macro; the preprocessor does not know the name of the current function. This macro is used to get the name of the current function. (C23) an optional list of attributes, applied to the function. See the following example to get the idea. MESA Developers thinks that this issue doesn't relate to MESA. Optimization is a non-factor since it is a compile time macro expansion; it will never affect performance in any way. 4.10 事前定義済み __func__ シンボルの関数名としての使用. For instance, you could create a wide character version of the function's name by using token pasting. If one deals with C++ code where a function name may not uniquely identify a function (that may happen even within the same file), something like __class__ or __FUNCTION__ may be much better. It's here temporarily, and the second method is effective) #include "StdAfx.h". Most should provide the __func__ macro but you have to . __func__ [predefined identifier, ISO C99], __FUNCTION__ [extension macro] 먼저 __func__는 컴파일러에 의해 자동으로 정의되는 const char* 형(type)의 상수이다.

Discussion on: Macro with current function name - __func__ vs __FUNCTION__. 1. The _PRETTY_FUNCTION__ is used to return the detail about the function. C99 has __func__, but for C++ this will be compiler specific.On the plus side, some of the compiler-specific versions provide additional type information, which is particularly nice when you're tracing inside a templatized function/class. This is currently stalled because we've confirmed that the linux_android_rel_ng build environment is non-standards-compliant; it treats __func__ like __PRETTY_FUNCTION__ instead of __FUNCTION__ and causes test failures if we switch. [PATCH] xtensa: replace remaining __FUNCTION__ occurance From: Harvey Harrison Date: Mon Mar 03 2008 - 14:29:56 EST Next message: Christoph Lameter: "Re: [PATCH] alloc_percpu() fails to allocate percpu data" Previous message: Adrian Bunk: "sparc vs. gcc 4.3" Messages sorted by: The predefined identifier __func__ was added to the 1999 ISO C standard; the older 1990 C standard doesn't have it..

It will always report the right file and line (and function if you choose to use __FUNCTION__ / __func__ ). When the name of a macro is recognized in the program source text, or in the arguments of certain other preprocessor commands, it's treated as a call to that macro. (2) Change,, name (test valid) __func__ replace to __FUNCTION__. MSVC supports the predefined preprocessor macros required by the ANSI/ISO C99, C11, and C17 standards, and the ISO C++14, C++17, and C++20 standards. __FUNCTION__ là không chuẩn, __func__ tồn tại trong C99 / C ++ 11. The others ( __LINE__ and __FILE__) are just fine. std:: source_location. Returns a null-terminated const char array of characters that contains the function name. Both of these are strings containing the name of the current function (there are slight semantic differences; see the GCC manual). I know that condition expression, which is argument of my macro, can . Basically the __FUNCTION__ and __func__ are same. The source_location class represents certain information about the source code, such as file names, line numbers, and function names. __func__ es un identificador declarado implícitamente que se expande a una variable de matriz de caracteres que contiene el nombre de la función cuando se usa dentro de una función.
