- *
- * Description:
- *
- * This plugin will use the /bin/df command to check the free space on
- * currently mounted filesystems. If the percent used disk space is
- * above <c_dfp>, a STATE_CRITICAL is returned. If the percent used
- * disk space is above <w_dfp>, a STATE_WARNING is returned. If the
- * specified filesystem cannot be read, a STATE_CRITICAL is returned,
- * other errors with reading the output result in a STATE_UNKNOWN
- * error.
- *
- * Notes:
- * - IRIX support added by Charlie Cook 4-16-1999
- * - Modifications by Karl DeBisschop 1999-11-24
- * reformat code to 80 char screen width
- * set STATE_WARNING if stderr is written or spclose status set
- * set default result to STAT_UNKNOWN
- * initailize usp to -1, eliminate 'found' variable
- * accept any filename/filesystem
- * use sscanf, drop while loop
- *
