(* Title: saveas.h
* Purpose: export of data by dragging icon from dialogue box
*
*)
#ifndef __saveas_h
#define __saveas_h
#ifndef __xfersend_h
#include "xfersend.h"
#endif
(* ----------------------------- saveas -------------------------------------
* Description: Displays a dialogue box, for the user to export application
* data.
*
* Parameters: int filetype -- type of file to save to
* char *name -- suggested file name
* int estsize -- estimated size of the file
* xfersend_saveproc -- caller-supplied function for saving
* application data to a file
* xfersend_sendproc -- caller-supplied function for RAM
* data transfer (if application is able
* to do this)
* xfersend_printproc -- caller-supplied function for printing
* application data, if "save icon" is
* dragged onto printer application
* void *handle -- handle to be passed to handler functions
* Returns: TRUE if data exported successfully.
* Other Info: This function displays a dialogue box with the following
* fields:
* i) a sprite icon appropriate to the given file type
* ii) the suggested filename
* iii) an OK button
* (Note: a template called "xfer_send" must be in the
* application's templates file to use this function, set up
* as in the !Edit, !Draw and !Paint applications)
* Xfersend deals with the complexities of message-passing
* protocols to achieve the data transfer. Refer to the
* typedefs in xfersend.h for an explanation of what the
* three caller-supplied functions should do.
* If you pass 0 as the xfersend_sendproc, then no in-core
* data transfer will be attempted
* If you pass 0 as the xfersend_printproc, then the file
* format for printing is assumed to be the same as for saving
* The estimated file size is not essential, but may improve
* performance.
*
