Subject: Change to using void * for character function content parameter
X-Git-Url: https://git.sommitrealweird.co.uk/onak.git/commitdiff_plain/f3143629476bae20f5310bbc0a59fe735b5d245d

Change to using void * for character function content parameter

  We were passing unsigned char * as the parameter to all of the
  character fetching/putting functions. Use void * instead so that
  we can pass other types of data without needlessly having to cast.
