std::move_only_function满足MoveConstructible和MoveAssignable的要求,但不满足CopyConstructible或CopyAssignable。这意味着它只能通过移动操作进行构造和赋值,不能进行复制操作。这种设计使得std::move_only_function能够处理那些不可复制的可调用对象,例如捕获了std::unique_ptr的lambda表达式。
GCC 有个 C 语言扩展修饰符 __attribute__((constructor)),可以让由它修饰的函数在 main() 之前执行,若它出现在共享对象中时,那么一旦共享对象被系统加载,立即将执行 __attribute__((constructor)) 修饰的函数。 代码语言:javascript 代码运行次数:0 运行 复制 #include <stdlib.h> #include <string.h> __...
