externals/zexy/src fwriteln.c,1.8,1.9 - Pd-cvs

23 Sep 2007


      Update of /cvsroot/pure-data/externals/zexy/src
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv9317
Modified Files:
    fwriteln.c 
Log Message:
made the best out of "fwriteln": now accepts also arguments "f" "g" and "e" as floating point formats and is verbose in case of erroneous usage.
