WebJul 21, 2024 · The first method reads a 32 bit value using the computer's natural byte ordering, and then swaps the bytes if bswap is true. The second method reads a 32 bit value in little endian format (if bswap is false) or big endian format (if bswap is true). On a little endian machine, they are equivalent. On a big endian machine, they perform opposite. WebThis document briefly describes the byte swapping required when a binary file created on a DOS/WIndows is to be read on a computer which has its bytes ordered the other way.
