DESCRIPTION

       These commands enable adding to and manipulation of the ADP output buffer.  See ns_adp for an overview on
       ADP pages.

       ns_adp_append string ?string ...?
              This  command  appends  one  or  more  strings to the ADP output buffer.  For the case of a single
              argument, it is equivalent to ns_adp_puts -nonewline string.

       ns_adp_close
              This command can be used to flush  and  close  the  underlying  HTTP  connection.   ADP  execution
              continues  after  the connection is closed; any text appended to the output buffer after the close
              is simply discarded when processing is complete.

       ns_adp_dump
              This command returns the text of the ADP buffer.

       ns_adp_flush
              This command flushes the contents of the ADP buffer to the current connection or file channel.  It
              will  raise a Tcl exception if the underlying flush failed, for example, if the HTTP connection is
              closed or the channel write failed.  Flushed content is returned in "chunked-encoding"  format  if
              the  HTTP protocol version is at least 1.1 (normally the case for all modern browsers).  A call to
              ns_adp_flush is not normally  needed  except  for  specialized  applications  as  all  content  is
              automatically  flushed  at the end of a connection or on buffer overflow.  (see ns_adp_ctl bufsize
              for details on buffer mangement).

       ns_adp_puts ?-nonewline? string
              This function appends the specified string to the ADP  buffer.   Unless  the  optional  -nonewline
              argument is used, a newline will be appended to the page after the string.  Note that the argument
              to ns_adp_puts is a single string unlike ns_adp_append which takes a variable number of strings to
              append.

       ns_adp_stream
              This  function  begins  streaming mode for the ADP. All data currently in the ADP output buffer is
              flushed and any subsequent data will be output directly to the connection.  It is equivalent to an
              ns_adp_flush followed by an ns_adp_ctl bufsize 0.

       ns_adp_tell
              This  function  returns the total number of bytes current in the ADP buffer.  A buffer overflow or
              direct call to ns_adp_flush will reset this counter to zero so the result of ns_adp_tell  may  not
              return the total number of bytes eventually sent.

       ns_adp_trunc ?length?
              This  function  can be used to truncate output buffer to the requested size. This can be useful to
              trim unintended white space or to clear a result and generate an error message.  Note that content
              already streamed to the client, if any, cannot be truncated.

       ns_puts ?-nonewline? string
              This command is a deprecated name for ns_adp_puts.
