Is there literature how to learn C, C++ for Linux audio, when learning C, C++ from the beginning? What kind of C, C++ code needs to be avoided and what kind of programming is existential etc.. I still got some hints, but some books, e-books might be better. - Ralf _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
