BT_ZERO(args_admin);

 

BfvLineDetach (lp, &args_admin);

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

You can replace some low-level functions with a high-level function, 

for example: 

See the applications in the sample application directory for more 

detailed information.

One way to send a fax using function calls for noninfopkt-formatted 

raw G3 files is demonstrated below. Each function is presented in 

sequential order, and the action it performs is described beneath it.

This example sends a two-page fax whose page and strip data are 

stored in noninfopkt-formatted files. The first page consists of a 

Group 3 letterhead (ltrhd.g3), a body in ASCII (main.txt), and a 

signature file in Group 3 (sig.G3). The second page is an ASCII file 

(memo.txt).

BT_ZERO(args_admin);

 

args_admin.unit = unit;

 

lp = BfvLineAttach(&args_admin);

Attaches to a free channel and gets a line pointer.

args_admin.config_file_name = "usrcnfig.cfg";

 

BfvLineReset(lp,&args_admin);

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

the user-defined configuration file named usrcnfig.cfg.

BT_ZERO(args_tel);

 

args_tel.phonenum = "w7814499009";

 

args_tel.call_protocol_code = CALL_PROTOCOL_FAX;

 

args_tel.func = userfunc;

 

args_tel.arg = userarg;

 

BfvLineOriginateCall(lp,&args_tel);

Dials the phone number, monitors call progress, calls the user 

function to optionally decide when to terminate call progress.

BfvFaxBeginReceive 

BfvFaxGetRemoteInfo 

BfvFaxSetLocalId 

BfvFaxWaitForTraining 

These low level functions are 

replaced with the high level function
