For ease of development, it applies (and tests) correctly on the +machine of the author; no other guarantees can be given. +It should give you a good idea of what is REQUIRED to make a copy of PDCLib +work. There is a lot more you could do, and even some things you SHOULD do, in +order to experience anything but abysmal performance: + +- Read / write operations on binary streams, and even on text streams for + machines that do not do any text conversion, can be made much more efficient + by using some sort of page buffer instead of the linear buffer implemented + here. It requires some special and platform-dependent manipulations, though, + which is why it is not done by default. + +- Anything relating to floating point logic is written in generic C. While + this is (hopefully) highly portable and should get you started on your + platform of choice, it is also highly inefficient and should be replaced by + inline assembly. Just make sure that your assembly keeps all the promises + the C library makes. + -- 2.40.0
