NAME
       tt_file_objects_query -- find all objects in the named file

SYNOPSIS
       #include <Tt/tt_c.h>
       Tt_status tt_file_objects_query(
       const char *filepath,
       Tt_filter_function filter,
       void *context,
       void *accumulator);

DESCRIPTION
       The  tt_file_objects_query  function instructs the ToolTalk service to find all objects in the named file and pass the objids to the filter
       function.  The context pointer and accumulator pointer initially specified are also passed to the filter function.

       As the ToolTalk service finds each object, it calls the filter function, passing the objid of the object and the  two  application-supplied
       pointers.   The filter function performs its computation and returns a Tt_filter_action value that tells the query function whether to con-
       tinue or to stop.  Tt_filter_action values are:

       TT_FILTER_CONTINUE
		 The query function should continue.

       TT_FILTER_STOP
		 The query function should stop.

       The filepath argument is the name of the file to be searched for objects.  The filter argument is the filter function to which  the  objids
       are  to be passed.  The context argument is a pointer to any information the filter needs to execute.  The ToolTalk service does not inter-
       pret this argument, but passes it directly to the filter function.  The accumulator argument is a pointer to where the filter is  to  store
       the  results of the query and filter operations.  The ToolTalk service does not interpret this argument, but passes it directly to the fil-
       ter function.

RETURN VALUE
       Upon successful completion, the tt_file_objects_query function returns the status of the operation as one of the following  Tt_status  val-
       ues:

       TT_OK	 The operation completed successfully.

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

       TT_ERR_PATH
		 The specified pathname included an unsearchable directory.

       TT_WRN_STOPPED
		 The query operation being performed was halted by Tt_filter_function.
