编译时存在的内存不同于运行时的内存。但是,您可以将地址作为模板参数传递,并在运行时执行转换:
You can cast an integer to a pointer and vice versa. In all cases, the destination pointer must be large enough to hold the result. Casting a null pointer results in a null pointer of the destination type. Any other cast results in undefined behavior....
分享44赞 c++吧 无语的lego 【求助】如何将integer转化成pointerRT,使用reinterpret_cast给出error: reinterpret_cast from integer to pointer.以前用的gcc4.9没有这个问题,但查到好像是对c++11标准的支持不完善。现在用的是gcc6.1。尝试过C-style cast但是和reinterpret_cast是一样的。求大神指教,... 分享28赞 ...
