|

| <h3>Synopsis</h3>

 | |
| <h3>Description</h3>
 | |
| <p>
 | |
| <tt>bigfile</tt> creates a file of the specified size in chunks of the
 | |
| specified chunk size.
 | |
| The default chunk size is 10, which is excessively small.
 | |
| The largest chunk size supported is 8192.
 | |
| The file size is rounded up to an integral number of chunks.
 | |
| Very small chunk sizes are not fully honored.
 | |
| </p>
 | |
| 
 | |
| <h3>Requirements</h3>
 | |
| <p>
 | |
| <tt>bigfile</tt> uses the following system calls:
 | |
| <ul>
 | |
| <li> <A HREF=../syscall/open.html>open</A>
 | |
| <li> <A HREF=../syscall/write.html>write</A>
 | |
| <li> <A HREF=../syscall/close.html>close</A>
 | |
| <li> <A HREF=../syscall/_exit.html>_exit</A>
 | |
| </ul>
 | |
| </p>
 | |
| 
 | |
| <p>
 | |
| <tt>bigfile</tt> should run on emufs once the basic system calls are
 | |
| complete, and should run on SFS once the file system assignment is
 | |
| complete. Sufficiently small files should work on SFS even before
 | |
| that point.
 | |
