Two examples are nothrow and constexpr.</p> <p>My understanding is that the compiler is not be allowed to infer those attributes, because a later change in the implementation might result of them not being satisfied anymore, and if a user used them depending on the inferred modifier, their code would break.</p> <p>Now, enter modules!</p> <p>In the new world, when the compiler processes a module, it can keep track of 2 informations: 1. what specifier is part of the function contract 2. what specifier can be inferred</p> <p>When using the module, the compiler can make sure that the contract is respected, but when compiling, it can leverage the inferred specifier.</p> <p>E.g.</p> <pre><code>int foo() { return 4; } </code></pre> <p>The compiler would allow to call this only in a non-constexpr context, but when calling it, it can leverage the fact that it&#39;s both constexpr and nothrow to improve code generation.</p> <p>Or if a vector could leverage this information in a move constructor to chose a more efficient reallocation strategy.</p> <p>Is the fact that compiler could keep track of the effective property of the code, transitively, a new potential way to gain runtime performances?</p> <p>I see this being useful for all those uses where it&#39;s not critical enough to spend the time to correctly label everything, or maybe you don&#39;t want to commit to the specific constraint of the specifier, but there would still be a performance improvement if this work was done.</p> <p>Thoughts?</p> </div><!-- SC_ON --> &#32;

Once I am comfortable doing that, I want to get into actual audio programming (for art projects and maybe game audio). I know this will take years.</p> <p>I think the best starting point for me would be some tutorials to follow for games (since these seem to cover all the topics needed for multimedia and later audio). Most of the music languages have a C Api with some sort of C++ Api built on top, so I would prefer to stick to somewhat of a C-style C++ for now. Handmade Hero seems like a great series to follow, but it is extremely long. Are there similar series that I could follow that deal with smaller projects?</p> <p>Thank you for your help!</p> </div><!-- SC_ON --> &#32; submitted by &#32; <a href="https://www.reddit.com/user/sopranosaxophone"> /u/sopranosaxophone </a> <br/> <span><a href="https://www.reddit.com/r/cpp/comments/10kxn7w/learning_c_for_multimedia_and_audio_programming/">[link]</a></span> &#32; <span><a href="https://www.reddit.com/r/cpp/comments/10kxn7w/learning_c_for_multimedia_and_audio_programming/">[comments]</a></span></content><id>t3_10kxn7w</id><link href="https://www.reddit.com/r/cpp/comments/10kxn7w/learning_c_for_multimedia_and_audio_programming/" /><updated>2023-01-25T12:36:19+00:00</updated><published>2023-01-25T12:36:19+00:00</published><title>Learning C++ for Multimedia and Audio programming</title></entry><entry><author><name>/u/mttd</name><uri>https://www.reddit.com/user/mttd</uri></author><category term="cpp" label="r/cpp"/><content type="html">&#32; submitted by &#32; <a href="https://www.reddit.com/user/mttd"> /u/mttd </a> <br/> <span><a href="https://programming-journal.org/2023/7/4/">[link]</a></span> &#32; <span><a href="https://www.reddit.com/r/cpp/comments/10l8kqw/revisiting_language_support_for_generic/">[comments]</a></span></content><id>t3_10l8kqw</id><link href="https://www.reddit.com/r/cpp/comments/10l8kqw/revisiting_language_support_for_generic/" /><updated>2023-01-25T20:19:57+00:00</updated><published>2023-01-25T20:19:57+00:00</published><title>Revisiting Language Support for Generic Programming: When Genericity Is a Core Design Goal</title></entry><entry><author><name>/u/spr00ge</name><uri>https://www.reddit.com/user/spr00ge</uri></author><category term="cpp" label="r/cpp"/><content type="html"><!-- SC_OFF --><div class="md"><p>Hi there, I often stumble upon fragments of the Boost libraries when I read other people’s code.
