Connect to a Wayland socket
Other Alias
wl_display_connect
SYNOPSIS
#include <wayland-client.h>
-
struct wl_display *wl_display_connect(const char *name);
-
struct wl_display *wl_display_connect_to_fd(int fd);
DESCRIPTION
wl_display_connect
connects to a Wayland socket that was previously opened by a Wayland server. The server socket must be placed in
XDG_RUNTIME_DIR
for this function to find it. The
name
argument specifies the name of the socket or
NULL
to use the default (which is
"wayland-0"). The environment variable
WAYLAND_DISPLAY
replaces the default value. If
WAYLAND_SOCKET
is set, this function behaves like
wl_display_connect_to_fd
with the file-descriptor number taken from the environment variable.
wl_display_connect_to_fd
connects to a Wayland socket with an explicit file-descriptor. The file-descriptor is passed as argument
fd.
RETURN VALUE
wl_display_connect
and
wl_display_connect_to_fd
return a new display context object or NULL on failure.
errno
is set correspondingly.
