dart:ffi internally calculates the fields offsets of structs in order to enable loading/storing from/to those fields. However, sometimes one would like to pass a pointer to a field inside a struct to C. For that use case we should expose the internal offsets. One way we could do this,...

OpenSSL keeps ABI/binary compatibility with minor releases or letter releases. So all structs offsets and macro constants are kept same.If you plan to use this library on an untested version of OpenSSL (like custom builds or pre releases), this can be a good source to consult....
