NAME            close  --  close a file



SYNOPSIS        (file descriptor in r0)

                sys close  / close = 6.



DESCRIPTION     Given a file descriptor such as returned from an

                open or creat call, close closes the associated

                file.  A close of all files is automatic on exit,

                but since processes are limited to 10 simultane-

                ously open files, close is necessary for programs

                which deal with many files.



SEE ALSO        creat(II), open(II)



DIAGNOSTICS     The error bit (c-bit) is set for an unknown file

                descriptor.
