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 simultaneously open files, close is
              necessary to programs which deal with many files.

              descriptor.
