##   RETURNS:     the value of the item if successful; semi-colon ';' otherwise
##                (semi-colon because any other characters could be used as the
##                  value, so use "\;" when comparing ini_read's return value)

##   PROCEDURE:   ini_write <ini file> <section> <item> [value]
##   DESCRITPION: Sets the value of item in the specified section in the ini
