19 * This program will grow a list of files.
20 * Each file will grow by grow_incr before the same
21 * file grows twice. Each file is open and closed before next file is opened.
23 * To just verify file contents: growfiles -g 0 -c 1 filename
25 * See help and prt_examples functions below.
29 * print debug message about options used
30 * setup signal handlers
31 * return control to user (if wanted - default action)
32 * fork number of desired childern (if wanted)
33 * re-exec self (if wanted)
34 * Determine number of files
35 * malloc space or i/o buffer
36 * Loop until stop is set
37 * Determine if hit iteration, time, max errors or num bytes reached
38 * Loop through each file
40 * fstat file - to determine if file is a fifo
41 * prealloc file space (if wanted)
50 * remove all files (if wanted)
