| void bt_close |
( |
void * |
handle | ) |
|
Closes the resource opened by bt_open.
- Parameters
-
| [in] | device | handle returned by bt_open |
- See also
- implementation at bt-win.c and bt-unix.c
Closes the resource opened by bt_open.
- Parameters
-
Closes the resource opened by bt_open.
- Parameters
-
| [in] | handle | handle returned by bt_open |
- Bug:
- It takes whopping 3 seconds for the COM port to be reclaimable. If opened before that, the device is unusable for a minute.

open a bluetooth device described by device. NULL leads to default action
- Parameters
-
| [in] | file_in | string describing the bluetooth device |
| [in] | only | for *nix: non-NULL for cases where read/write files differ |
- Returns
- handle a opaque handle for use with bt_{read,write,close,error}

- Parameters
-

- Returns
- HANDLE Windows HANDLE to virtual COM port for use with bt_{read,write,close,error}

| |
writes buf[1] till buf[count - 2] to device
- Parameters
-
| [in] | device | handle returned by bt_open |
| [in] | buf | buffer to write to |
| [in] | count | number of characters to be read |
| [in] | milliseconds | number of milliseconds to wait at maximum. -1 is indefinitely |
- Returns
- status -1 on error. bytes read otherwise.
- Bug:
- the milliseconds part needs to be tested more throughly
- See also
- implementation at bt-win.c and bt-unix.c
- Parameters
-
| [in] | device | handle returned by bt_open() |
| [in] | buf | buffer to write to |
| [in] | count | number of characters to be read |
| [in] | milliseconds | number of milliseconds to wait at maximum. -1 is indefinitely |
- Returns
- status -1 on error. bytes read otherwise.
- Bug:

- Parameters
-
| [in] | device | handle returned by bt_open |
| [in] | buf | buffer to write to |
| [in] | count | number of characters to be read |
| [in] | milliseconds | is ignored |
- Returns
- status -1 on error. bytes read otherwise.
- Bug:
- milliseconds is ignored

| |
writes buf[1] till buf[count - 2] to device
- Parameters
-
| [in] | device | handle returned by bt_open |
| [in] | buf | byte string to write, the first byte is omitted |
| [in] | count | number of characters to be written (including leading ignored byte) |
- Returns
- status -1 on error. bytes read otherwise.
- Bug:
- the first byte is omitted for compatiblity with the leading report byte demanded by
hid_write. Wrapping HIDAPI could fix this. - See also
- implementation at bt-win.c and bt-unix.c

- Returns
- status -1 on error. bytes read otherwise.
