Next we take the byte offset of the field y(4, under the x86-64 ABI we are using), counting from the beginning of the struct, and add that to p. Finally, we retrieve the integer stored at the address p+4. In C, we could write this symbolically using WebMay 30, 2024 · Check your compiler documentation. Keep in mind that not padding structures has a run time cost, so you should only do this when your struct defines a storage or transmission data format. static_assert(sizeof(Data) == 132, "You forgot to disable padding!"); You can get the size of the struct and memcpy that many bytes. diamond car insurance reviews 2015 https://thebankbcn.com
