    CLOSE(II)                     8/5/73                    CLOSE(II)

    NAME
         close  -  close a file

    SYNOPSIS
         (close = 6.)
         (file descriptor in r0)
         sys close

         close(fildes)

    DESCRIPTION
         Given  a file descriptor such as returned from an open, cre-
         at, or pipe call, close closes the associated file.  A close
         of  all  files is automatic on exit, but since processes are
         limited to 15 simultaneously open files, close is  necessary
         for programs which deal with many files.

    SEE ALSO
         creat(II), open(II), pipe(II)

    DIAGNOSTICS
         The error bit (c-bit) is set for an unknown file descriptor.
         From C a -1 indicates an error, 0 indicates success.
