wayland-sys 0.7.8

FFI bindings to the wayland system libraries. The names exported by this crate should *not* be used directly, but though the `ffi_dispatch` macro like this: ```ignore ffi_dispatch!(HANDLE_NAME, func_name, arg1, arg2, arg3); ``` Where `HANDLE_NAME` is the name of the handle generated if the cargo feature `dlopen` is on. For this to work, you must ensure every needed symbol is in scope (aka the static handle if `dlopen` is on, the extern function if not). The easiest way to do this is to glob import the appropriate module. For example: ```no_run #[macro_use] extern crate wayland_sys; use wayland_sys::client::*; fn main() { let display_ptr = unsafe { ffi_dispatch!(WAYLAND_CLIENT_HANDLE, wl_display_connect, ::std::ptr::null()) }; } ``` Each module except `common` corresponds to a system library. They all define a function named `is_lib_available()` which returns a boolean depending on whether the lib could be loaded. They always return true if the feature `dlopen` is absent, as the lib is then directly linked.
