[][src]Crate wayland_sys

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:

This example is not tested
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:

This example is not tested
#[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.
