Dear R Devel, Since Linux moved away from using a file-system interface for audio, I think it is necessary to write special libraries to interface with audio hardware from various languages on Linux.
In R, it seems like the appropriate datatype for a `snd_pcm_t` handle pointing to an open ALSA source or sink would be a "connection". Connection types are already defined in R for "file", "url", "pipe", "fifo", "socketConnection", etc. Is there a tutorial or an example package where a new type of connection is defined, so that I can see how to do this properly in a package? I can see from the R source that, for example, `do_gzfile` is defined in `connections.c` and referenced in `names.c`. However, I thought I should ask here first in case there is a better place to start, than trying to copy this code. I only want an object that I can use `readBin` and `writeBin` on, to read and write audio data using e.g. `snd_pcm_writei` which is part of the `alsa-lib` package. Thank you very much, Frederick ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
