怎么解决warninguint32_thigh 1uint32_tlow2uint64_t ContentSize (high 32ULL) | low编译报warni

怎么解决warning
uint32_t high =1
uint32_t low=2
uint64_t ContentSize = (high << 32ULL) | low;
编译报
warning: left shift count >= width of type

[解决办法]
int的左移最多 31位，超过了肯定错误啊

改为
uint64_t high =1
uint64_t low=2
uint64_t ContentSize = (high << 32ULL) | low;

[解决办法]
+1 原来是这样
