 | |
| <h4 align=center>OS/161 Reference Manual</h4>
 | |
| 
 | |
| <h3>Name</h3>
 | |
| <p>
 | |
| crash - commit various exceptions
 | |
| </p>
 | |
| 
 | |
| <h3>Synopsis</h3>
 | |
| <p>
 | |
| <tt>/testbin/crash</tt> [<em>operation</em>]
 | |
| </p>
 | |
| 
 | |
| <h3>Description</h3>
 | |
| <p>
 | |
| <tt>crash</tt> will perform any one of fourteen illegal processor
 | |
| operations, any one of which should get it killed without causing the
 | |
| whole system to crash.
 | |
| </p>
 | |
| 
 | |
| <p>
 | |
| The operations are coded <tt>a</tt> through <tt>n</tt> and may be
 | |
| chosen on the command line. If no operation is chosen, a menu is
 | |
| displayed and a choice solicited.
 | |
| </p>
 | |
| 
 | |
| <h3>Restrictions</h3>
 | |
| <p>
 | |
| Test <tt>f</tt>, which writes into the process's own code segment,
 | |
| will only cause a processor exception if you implement read-only code
 | |
| segments. Since this is not required, it is not required that test
 | |
| <tt>f</tt> pass.
 | |
| </p>
 | |
| 
 | |
| <p>
 | |
| However, using test <tt>f</tt> must not under any circumstances
 | |
| corrupt the code in the copy of <tt>crash</tt> on disk!
 | |
| </p>
 | |
| 
 | |
| <h3>Requirements</h3>
 | |
| <p>
 | |
| <tt>crash</tt> uses the following system calls:
 | |
| <ul>
 | |
| <li> <A HREF=../syscall/read.html>read</A>
 | |
| <li> <A HREF=../syscall/write.html>write</A>
 | |
| <li> <A HREF=../syscall/_exit.html>_exit</A>
 | |
| </ul>
 | |
| </p>
 | |
| 
 | |
| <p>
 | |
| <tt>crash</tt> should operate properly once the basic system call
 | |
| assignment is complete.
 | |
