<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.
|
|

|
|
|
|
<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.
