2 Jan 2007


      Update of /cvsroot/pure-data/externals/io/hidio
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv12320
Modified Files:
    hidio.c hidio.h hidio_darwin.c hidio_linux.c hidio_windows.c 
Log Message:
I cleaned up the return values.  This is what I used:
* EXIT_SUCCESS for successful conditions
* -1 for failure when a device number is being returned
* EXIT_FAILURE for all other failures
EXIT_SUCCESS and EXIT_FAILURE are defined in stdlib.h
