Well, I like me some bit-fields myself, when I can use them. The fact though is that they are famously unportable, and therefore less than useful when dealing with binary formats over a network. N1570 (the final draft of the C11 standard) says under 6.7.2.1,

> The order of allocation of bit-fields within a unit (high-order to low-order or low-order to high-order) is implementation-defined. The alignment of the addressable storage unit is unspecified.

I would say that it is best to keep that in mind.

Thank you!
