NAME
     ttdt_sender_imprint_on - act like a child of  the  specified
     tool

SYNOPSIS
     #include <Tt/tttk.h>
     Tt_status ttdt_sender_imprint_on(const char *handler,
                                      Tt_message contract,
                                      char **display,
                                      int *width,
                                      int *height,
                                      int *xoffset,
                                      int *yoffset,
                                      XtAppContext app2run,
                                      int ms_timeout);

DESCRIPTION
     The ttdt_sender_imprint_on() function is used  to  make  the
     calling  tool  act equivalently to a child of another speci-
     fied tool.  The calling tool adopts  the  other  tool's  X11
     display,  locale,  and  current  working directory.  It also
     learns the other tool's X11 geometry, so that it  may  posi-
     tion itself appropriately.

     If the  handler  argument  is  non-NULL,  the  requests  are
     addressed  to  that  procid using TT_HANDLER.  If handler is
     NULL and the contract argument is non-NULL, the requests are
     addressed to the tt_message_sender(3) of the contract, using
     TT_HANDLER.

     The contract argument is passed to tttk_message_create(3) as
     the context argument.

     If     the     display     argument     is     not     NULL,
     ttdt_sender_imprint_on() returns the other tool's display in
     *display.  If display is NULL, ttdt_sender_imprint_on() sets
     the   DISPLAY  environment  variable  to  the  other  tool's
     display.

     If each of the width, height, xoffset, and yoffset arguments
     are  NULL,  then  ttdt_sender_imprint_on() does not send the
     other tool a Get_Geometry request.

     The ttdt_sender_imprint_on() function passes the app2run and
     ms_timeout arguments to tttk_block_while(3), blocking on the
     replies to the requests it sends.

     If     the     display     argument     is     not     NULL,
     ttdt_sender_imprint_on()  sets *display to a string that can
     be freed with tt_free().


     If for some reason no width or height  is  returned  by  the
     other  tool, ttdt_sender_imprint_on() sets *width or *height
     to  -1.   If  no   positional   information   is   returned,
     ttdt_sender_imprint_on()   sets  *xoffset  and  *yoffset  to
     {INT_MAX}.

RETURN VALUE
     Upon  successful  completion,  the  ttdt_sender_imprint_on()
     function  returns  the status of the operation as one of the
     following Tt_status values:

        TT_OK   The operation completed successfully.

        TT_DESKTOP_ETIMEDOUT
                One or more of the sent requests did not complete
                within ms_timeout milliseconds.

        TT_ERR_NOMEM
                There is insufficient memory available to perform
                the function.

        TT_ERR_NOMP
                The ttsession(1) process is not running  and  the
                ToolTalk service cannot restart it.

        TT_ERR_OVERFLOW
                The ToolTalk service  has  more  active  messages
                than  it  can  handle.   (The  maximum  number of
                active messages is implementation  specific,  but
                is at least 2000.)

        TT_ERR_PROCID
                The specified process identifier is out  of  date
                or invalid.

APPLICATION USAGE
     If both the handler and contract are zero, the requests  are
     addressed to no tool in particular, using TT_PROCEDURE; this
     is not recommended.
