I am migrating legacy code written for the PowerPC platform to X86, and have been running into Endian issues throughout the code.
In the latest issue I've discovered, a section of code in which a record has been defined that has 111 components of various data types.
Is there any mechanism within Ada that would provide a way to iterate across all components of a record, perhaps providing their data types?
Problem I have is that this record is used (via a MEMCPY call) to populate a buffer used to transmit an message via Ethernet. While I have adjusted the record's representation clause to put the data fields of the record into the correct bit location, those fields larger than a byte are of the wrong Endianness within the buffer.
Thanks,
