It would make sense to support struct elements and enum elements, but that has not been implemented. Char arrays are more controversial due to verification and zero termination and are also not supported. Arrays are aligned to the size of the first field and are equivalent to repeating elements...
Returns the text margin. Nonzero if successful; otherwise 0.RemarksThis member function emulates the functionality of the BCM_GETTEXTMARGIN message, as described in the Buttons section of the Windows SDK.CButton::SetBitmapCall this member function to associate a new bitmap with the button....
除了BUILD_BUG_ON,还有一些实用的宏同样能在编译期检查代码的静态约束: #define BUILD_BUG_ON_ZERO(e) (sizeof(struct { int:-!!(e); })) #define BUILD_BUG_ON_NULL(e) ((void *)sizeof(struct { int:-!!(e); })) 原理如下: 这2个宏利用了C语言结构体位字段长度不能为负数的性质,分别实现...
struct S1 { void f(int); void f(int, int); }; struct S2 { template <class C, void (C::*Function)(int) const> void f() {} }; void f() { S2 s2; s2.f<S1, &S1::f>(); } The current compiler correctly gives an error, because the template parameter type doesn't match...

嵌入式开发编程语言是C和汇编,本文讲的source文件指的是c和汇编文件。在平常开发中,我们只会关注自己创建的.c/.h/.s源文件,但实际上我们也跟很多不是我们创建的源文件在打交道,那么一个完整的嵌入式工程到底会包含哪些source文件呢? 大家好,我是痞子衡,是正经搞技术的痞子。今天痞子衡给大家讲的是嵌入式开发...
现在我们已经收集了足够的信息,可以开始讨论 CMake 的核心功能:构建项目。在 CMake 中,一个项目包含管理将我们的解决方案带入生活的所有源文件和配置。配置从执行所有检查开始:目标平台是否受支持,是否拥有所有必要的依赖项和工具,以及提供的编译器是否工作并支持所需功能。 完成后,CMake 将为我们的选择构建工具生成...
