xdgsurfacegettoplevel

xdgsurfacegettoplevel is a function within the Wayland protocol, a display server protocol that provides a framework for compositors to display graphical user interfaces. This function is part of the xdg-shell protocol, which is an extension to the Wayland protocol that provides a set of interfaces for desktop environments.

The xdgsurfacegettoplevel function is used to obtain the toplevel interface for a given xdg_surface. The toplevel interface represents a top-level surface, which is a surface that is not embedded within another surface. This function is typically used by clients, such as window managers or desktop environments, to interact with top-level surfaces.

The xdgsurfacegettoplevel function takes a single argument, which is a pointer to an xdg_surface. It returns a pointer to an xdg_toplevel interface, which can then be used to manipulate the properties of the top-level surface, such as its size, position, and state.

It's important to note that the xdg-shell protocol is still under development, and the xdgsurfacegettoplevel function may change or be deprecated in future versions of the protocol. Therefore, it's recommended to consult the latest documentation for the Wayland protocol and the xdg-shell protocol when using this function.
