Functions | |
void | ei_seat_set_user_data (struct ei_seat *seat, void *user_data) |
Set a custom data pointer for this context. | |
void * | ei_seat_get_user_data (struct ei_seat *seat) |
Return the custom data pointer for this context. | |
const char * | ei_seat_get_name (struct ei_seat *seat) |
bool | ei_seat_has_capability (struct ei_seat *seat, enum ei_device_capability cap) |
Return true if the capabilitiy is available on this seat or false otherwise. | |
void | ei_seat_bind_capabilities (struct ei_seat *seat,...) __attribute__((sentinel)) |
Bind this client to the given seat capabilities, terminated by NULL . | |
void | ei_seat_unbind_capabilities (struct ei_seat *seat,...) __attribute__((sentinel)) |
Unbind a seat's capabilities, terminatd by NULL . | |
struct ei_seat * | ei_seat_ref (struct ei_seat *seat) |
struct ei_seat * | ei_seat_unref (struct ei_seat *seat) |
struct ei * | ei_seat_get_context (struct ei_seat *seat) |
Return the struct ei context this seat is associated with. | |
The API to query and interact with a struct ei_seat
void ei_seat_bind_capabilities | ( | struct ei_seat * | seat, |
... ) |
Bind this client to the given seat capabilities, terminated by NULL
.
Once bound, the server may create devices for the requested capability and send the respective EI_EVENT_DEVICE_ADDED events. To undo, call ei_seat_unbind_capabilities().
Note that binding to a capability does not guarantee a device for that capability becomes available. Devices may be added and removed at any time.
It is an application bug to call this function for a capability already bound - call ei_seat_unbind_capabilities() first.
Calling this function for a capability that does not exist on the seat is permitted (but obviously a noop)
Return the struct ei context this seat is associated with.
const char * ei_seat_get_name | ( | struct ei_seat * | seat | ) |
void * ei_seat_get_user_data | ( | struct ei_seat * | seat | ) |
Return the custom data pointer for this context.
libei will not look at or modify the pointer. Use ei_seat_get_user_data() to change the user data.
bool ei_seat_has_capability | ( | struct ei_seat * | seat, |
enum ei_device_capability | cap ) |
Return true if the capabilitiy is available on this seat or false otherwise.
The return value of this function is not affected by ei_seat_confirm_capability().
void ei_seat_set_user_data | ( | struct ei_seat * | seat, |
void * | user_data ) |
Set a custom data pointer for this context.
libei will not look at or modify the pointer. Use ei_seat_get_user_data() to retrieve a previously set user data.
void ei_seat_unbind_capabilities | ( | struct ei_seat * | seat, |
... ) |
Unbind a seat's capabilities, terminatd by NULL
.
This function indicates the the application is no longer interested in devices with the given capability.
If any devices with the given capability are present, libei automatically calls ei_device_close() on those devices (and thus the server will send EI_EVENT_DEVICE_REMOVED for those devices).
