description of  the last system  call that failed.   The external
variable errno contains  the last error number.  Normally, string
is the perror of the command that failed or a file perror.

The external array sys_errlist gives the list of messages used by
perror.  The  external sys_nerr gives  the number of  messages in
the list.
