ttdt_Get_Modified(library call) 										   ttdt_Get_Modified(library call)

NAME

       ttdt_Get_Modified -- ask if any ToolTalk client has changes pending on a file

SYNOPSIS

       #include <Tt/tttk.h>
       int ttdt_Get_Modified(
       Tt_message context,
       const char *pathname,
       Tt_scope the_scope,
       XtAppContext app2run,
       int ms_timeout);

DESCRIPTION

       The ttdt_Get_Modified function sends a Get_Modified request in the scope the_scope and waits for the reply.  A Get_Modified request asks if
       any ToolTalk client has changes pending on pathname that it intends to make persistent.

       The context argument describes the environment to use.  If context is not zero, messages created by ttdt_Get_Modified inherit from  context
       all  contexts  whose slotname begins with the characters ENV_. That is, the environment described in context is propagated to messages cre-
       ated by ttdt_Get_Modified.

       The pathname argument is a pointer to a pathname on which the client is operating.

       The the_scope argument identifies the scope of the request.  If the_scope is TT_SCOPE_NONE, ttdt_Get_Modified tries TT_BOTH, and falls back
       to TT_FILE_IN_SESSION if, for example, the ToolTalk database server is not installed on the file server that owns pathname.

       The  ttdt_Get_Modified  function passes app2run and ms_timeout to tttk_block_while(3), blocking on the reply to the Get_Modified request it
       sends.

RETURN VALUE

       Upon successful completion, the ttdt_Get_Modified function returns non-zero if the  Get_Modified  request  receives  an	affirmative  reply
       within ms_timeout milliseconds; otherwise, it returns zero.

NAME

       ttdt_file_request -- create and send a standard ToolTalk request about a file

SYNOPSIS

       #include <Tt/tttk.h>
       Tt_message ttdt_file_request(
       Tt_message context,
       Tttk_op op,
       Tt_scope scope,
       const char *pathname,
       Ttdt_file_cb cb,
       void *client_data,
       int send_and_destroy);

DESCRIPTION

       The  ttdt_file_request  function  is  used  to create (and optionally send) any of the standard Desktop file requests such as Get_Modified,
       Save, and Revert.

       The ttdt_file_request function creates a request with the specified op and scope, and sets its file attribute  to  pathname.  The  function
       adds  an unset argument of Tt_mode TT_IN and vtype File to the request, per the Desktop messaging conventions.  If op is TTDT_GET_MODIFIED,
       ttdt_file_request also adds an unset TT_OUT argument of vtype Boolean to the request.  The ttdt_file_request function installs cb as a mes-
       sage  callback  for  the  created  request,  and  ensures that client_data will be passed into the callback.  (The Ttdt_file_cb callback is
       described under ttdt_file_join(3)). If send is True, ttdt_file_request sends the request before returning the handle to it;  otherwise,	it
       only creates the request.

       The  context argument describes the environment to use.	If context is not zero, messages created by ttdt_file_request inherit from context
       all contexts whose slotname begins with the characters ENV_.

RETURN VALUE

       Upon successful completion, the ttdt_file_request function returns the created Tt_message; otherwise, it returns  an  error  pointer.   The
       application can use tt_ptr_error(3) to extract one of the following Tt_status values from the returned handle:

       TT_ERR_DBAVAIL
		 The ToolTalk service could not access the ToolTalk database needed for this operation.

       TT_ERR_DBEXIST
		 The ToolTalk service could not access the specified ToolTalk database in the expected place.

       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 spe-
		 cific, but is at least 2000.)

       TT_ERR_POINTER
		 The pathname argument was NULL or was a ToolTalk error pointer.

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

APPLICATION USAGE

       The ttdt_file_request function is a lower-level interface than ttdt_Get_Modified, ttdt_Save, and ttdt_Revert, since  the  latter  functions
       create and send the request and then block on its reply.
