* This IOCTL is used to associate the current file descriptor with a
|
| 74 |
|
|
* FW Client (given by UUID). This opens a communication channel
|
| 75 |
|
|
* between a host client and a FW client. From this point every read and write
|
| 76 |
|
|
* will communicate with the associated FW client.

| 77 |
|
|
* Only in close() (file_operation release()) the communication between
|
| 78 |
|
|
* the clients is disconnected
|
| 79 |
|
|
*
|
| 80 |
|
|
* The IOCTL argument is a struct with a union that contains
|
| 81 |
|
|
* the input parameter and the output parameter for this IOCTL.
|
| 82 |
|
|
*
|
| 83 |
|
|
* The input parameter is UUID of the FW Client.
|
| 84 |
|
|
* The output parameter is the properties of the FW client
|
| 85 |
|
|
* (FW protocol version and max message size).
