{

BT_ZERO(args_fax);

args_fax.s_tp = tp;

args_fax.combine = 0;

if (BfvFaxNextPageTiff(lp,&args_fax) <= 0)

break;

BT_ZERO(args_fax);

args_fax.s_tp = tp;

if (BfvFaxSendPageTiff(lp,&args_fax) < 0)

break;

}

Loops through the TIFF-F file, getting the next page and sending it

to the driver.

BfvFaxEndOfDocument(lp, &args_fax);

Finishes up when the TIFF data is exhausted.

BT_ZERO(args_tiff);

args_tiff.tp = tp;

BfvTiffClose(&args_tiff);

Closes the TIFF-F file after the file is transmitted.

BT_ZERO(args_admin);

BfvLineDetach (lp, &args_admin);

Frees all the memory for the attached line and closes the device.

Receiving a Fax Using Calls for TIFF-F Files

One way to receive a fax using function calls for TIFF-F files is

demonstrated below. Each function is presented in sequential order,

and the action it performs is described beneath it.

BT_ZERO(args_admin);

args_admin.unit = unit;

lp = BfvLineAttach(&args_admin);

Attaches to a free channel and gets a BTLINE pointer.

args_admin.config_file_name = "usrcnfig.cfg";

BfvLineReset(lp,&args_admin);

Resets the channel and sets the user-configured options in the

user-defined configuration file named usrcnfig.cfg.

BT_ZERO(args_tiff);

args_tiff.fname = name;

args_tiff.fmode = "w";

tp = BfvTiffOpen(&args_tiff);

Opens the TIFF-F file name to store the received fax.
