Using
memcmp()to compare structures can be problematic, because of the padding between fields. The initializer is not guaranteed to set the padded areas to 0 (even if it usually does). When it does not, two structures may have identical fields bit-for-bit, butmemcmp()will report them as differing because of the different uninitialized padding.To resolve:
novas_equals_[...]()functions to the C99 API, and use these to perform comparisons between structures with typical 'sane' tolerances.structcomparison methods.equals(),operator==()andoperator!=()methods to more C++ classes, using the new C99 comparisons.
