WebMay 5, 2024 · Instead of bit manipulations, I suggested using a union of a bit field structure and a unsigned char array. I know that the order of bit fields is compiler dependent, but thought that would be easy to determine. HOWEVER, I got some results, which I find undeciferable. Here is the test code I created. WebApr 23, 2024 · Bit-fields can be used to allow flags or other integer values with small ranges to be packed together to save storage space. Bit-fields can improve the storage efficiency of structures. Compilers typically allocate consecutive bit-field structure members into the same int -sized storage, as long as they fit completely into that storage unit.
WebBit fields are supported in all compilers, but the implementations may differ. Some bit fields are stored left to right on one compiler, but right to left on another. Some compilers may …
