#149821 - Less non-portable? Responding to: ???'s previous message |
Oliver Sedlacek said:
To make unions more portable, I use macros that explicitly encapsulate compiler endian-ness. Note my added emphasis there: it doesn't make them completely portable - eg, on some architectures, the issue of padding or packing will arise... There may also be some architectures that cannot simply be described as either big- or little-endian; eg, the bytes within a "word" might little-endian, but the "words" within a multiple-"word" value might be big endian... (I seem to remember someone mentioning something like this to do with the PDP-8?) |
