为了允许传统和 CMake 配置在一段时间内共存,一个典型的策略是将所有 CMake 代码收集在CMakeLists.txt文件中,并将所有辅助 CMake 源文件放在cmake子目录下。在我们的示例中,我们不会引入cmake子目录,而是将辅助文件更靠近需要它们的目标和源文件,但我们会注意保持几乎所有用于传统 Autotools 构建的文件不变,只有...

(A large stack frame might occur if the function uses the stack heavily or is recursive.) The total stack size in user mode can be increased if stack overflow actually occurs, but only up to the system limit. You can use the/analyzecommand-line option to change the value for<constant 2...
This is a function, not a define, but for all practical purposes it will have same efficience while also supporting runtime endian detection where necessary. The flatbuffer environment only supports reading either big or little endian for the time being. To test which is supported, use the ...
Would it be better to return None if the object has been finalized? The idiom is that APIs returning a PyObject pointer only will return NULL in case of error. It's possible to return a strong reference to None if the reference is dead. But it makes the API harder to handle since yo...

创建unique指针声明很普通,而特殊点在于,其是独享被管理对象的,不允许两个指针同时指向(如果这样操作会报错),而想要赋值就只可以使用移动语义move将其所有权进行转移,而且转移后原有指针失去指向。 shared_ptr:shared_ptr也在实际应用中广泛使用。它的原理是使用引用计数实现对同一块内存的多个引用。在最后一个引用被...
