NAME            fstat  --  get status of open file

SYNOPSIS        (file descriptor in r0)

                sys     fstat; buf      / fstat = 28.

DESCRIPTION     This call is identical to stat, except that it

                operates on open files instead of files given by

                name.  It is most often used to get the status of

                the standard input and output files, whose names

                are unknown.
