 NAME    [Toc]    [Back]
      tt_file_objects_query - find all objects in the named file

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

 DESCRIPTION    [Toc]    [Back]
      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 applicationsupplied
 pointers.  The filter function performs its computation and
      returns a Tt_filter_action value that tells the query function whether
      to continue or to stop.  Tt_filter_action values are:

                The query function should continue.

                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 interpret 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 filter function.

 RETURN VALUE    [Toc]    [Back]
      Upon successful completion, the tt_file_objects_query function returns
      the status of the operation as one of the following Tt_status values:

      TT_OK     The operation completed successfully.

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

                The ToolTalk service could not access the specified ToolTalk
