- (* -------------------------- xferrecv_checkinsert -------------------------
- * Description: Set up the acknowledge message for a MDATAOPEN or MDATALOAD
- * and get filename to load from.
- *
- * Parameters: char **filename -- returned pointer to filename
- * Returns: the file's type (eg. 0x0fff for !Edit)
- * Other Info: This function checks to see if the last wimp event was a
- * request to import a file. If so it returns file type and
- * a pointer to file's name is put into *filename. If not
- * it returns -1.
- *

- (* --------------------------- xferrecv_insertfileok -----------------------
- * Description: Deletes scrap file (if used for transfer), and sends
- * acknowledgement of MDATALOAD message.
- *
- * Parameters: void
- * Returns: void.
- * Other Info: none.

- (* --------------------------- xferrecv_checkprint -------------------------
- * Description: Set up acknowledge message to a MPrintTypeOdd message
- * and get file name to print.
- *
- * Parameters: char **filename -- returned pointer to filename
- * Returns: The file's type (eg. 0x0fff for !Edit).
- * Other Info: Application can either print file directly or convert it to
- * <Printer$Temp> for printing by the printer application.

- (* --------------------------- xferrecv_printfileok ------------------------
- * Description: Send an acknowledgement back to printer application. If
- * file sent to <Printer$Temp> then this also fills in file
- * type in message.
- *
- * Parameters: int type -- type of file sent to <Printer$Temp>
- * (eg. 0x0fff for !edit)
- * Returns: void.
- * Other Info: none.

- * Description: Set up acknowledgement message to a MDATASAVE message.

- * Parameters: int *estsize -- sender's estimate of file size
- * Returns: File type.
- * Other Info: none.

- (* ------------------------- xferrecv_buffer_processor ---------------------
- * Description: This is a typedef for the caller-supplied function
- * to empty a full buffer during data transfer.
- *
- * Parameters: char **buffer -- new buffer to be used
- * int *size -- updated size
- * Returns: return FALSE if unable to empty buffer or create new one.
- * Other Info: This is the function (supplied by application,) which will
- * be called when buffer is full. It should empty the current
- * buffer, or create more space and modify size accordingly
- * or return FALSE. *buffer and *size are the current buffer
- * and its size on function entry.

- (* ---------------------------- xferrecv_doimport --------------------------
- * Description: Loads data into a buffer, and calls the caller-supplied
- * function to empty the buffer when full.
- *
- * Parameters: char *buf -- the buffer
- * int size -- buffer's size
- * xferrecv_buffer_processor -- caller-supplied function to
- * be called when buffer full
- * Returns: Number of bytes transferred on successful completion
- * or -1 otherwise.

- (* ---------------------- xferrecv_file_is_safe ----------------------------
- * Description: Informs caller if file was recieved from a "safe" source
- * (see below for definition of "safe").
- *
- * Parameters: void
- * Returns: true if file is safe.
- * Other Info: "Safe" in this context means that the supplied filename
- * will not change in the foreseeable future.
