lv_wayland_get_fd

Retrieves the file descriptor of the wayland socket

int lv_wayland_get_fd(void)

lv_wayland_get_output_count

Get the number of physical outputs (screens) advertised by the compositor

uint8_t lv_wayland_get_output_count(void)

Returns: uint8_t — the number of outputs, 0 if the driver isn't initialized yet

lv_wayland_get_output_name

Get the name of a physical output

const char * lv_wayland_get_output_name(uint8_t output)

Returns: const char * — the connector name, e.g. "HDMI-A-1", or NULL if output is out of range. The string is owned by the driver and stays valid until lv_wayland_deinit

lv_wayland_get_output_size

Get the size of a physical output

bool lv_wayland_get_output_size(uint8_t output, int32_t *width, int32_t *height)

Returns: bool — true if the size is known, false if output is out of range or the compositor hasn't reported a size yet

lv_wayland_get_display_size

Look up a physical output by name and get its size

int32_t lv_wayland_get_display_size(const char *name, int32_t *width, int32_t *height)

Returns: int32_t — the index of the output, to be passed to lv_wayland_window_set_physical_display, or -1 if no output goes by that name
