为什么.c文件可以包含块? [英] Why can .c files contain blocks?

问题描述

我认为block是Objective-C的功能.最近，我将代码块添加到了一些C源文件中，并且发现它可以正常编译.

I think block is the Objective-C feature. Recently I am adding the block to some C source file and I found it just compile OK.

对于* .c文件，我感到困惑，编译器(Clang)是否应该将其视为纯C文件，为什么它可以允许阻塞?

I get confused, for *.c file, should the compiler(Clang) consider it as the pure C file, why it can permit block?

推荐答案

实际上Clang引入了块

Actually Clang introduces blocks

到C，以及扩展到Objective-C，C ++和Objective-C ++

to C and, by extension, Objective-C, C++, and Objective-C++

您可以在概述中阅读此处.

当然，使用块会使您的源代码与C11标准不兼容，但是，您知道，只要您的代码仅适用于Mac OS X ...

Of course, using blocks makes your source incompatible with C11 standard but, you know, as long as your code is for Mac OS X only...

编辑:不知道，GCC中也提供了块.

EDIT: Blocks are also available in GCC, didn't know about it.
