<p>The names exported by this crate should <em>not</em> be used directly, but though
|
|
|
|
|
|
the <code>ffi_dispatch</code> macro like this:</p>
|
|
|
|
|
|
|
|
|
|
|
|
<div class='information'><div class='tooltip ignore'>ⓘ<span class='tooltiptext'>This example is not tested</span></div></div><div class="example-wrap"><pre class="rust rust-example-rendered ignore">

<span class="macro">ffi_dispatch</span><span class="macro">!</span>(<span class="ident">HANDLE_NAME</span>, <span class="ident">func_name</span>, <span class="ident">arg1</span>, <span class="ident">arg2</span>, <span class="ident">arg3</span>);</pre></div>
|
|
|
|
|
|
<p>Where <code>HANDLE_NAME</code> is the name of the handle generated if the cargo feature
|
|
|
|
|
|
<code>dlopen</code> is on.</p>
|
|
|
|
|
|
<p>For this to work, you must ensure every needed symbol is in scope (aka the static handle
|
|
|
|
|
|
if <code>dlopen</code> is on, the extern function if not). The easiest way to do this is to glob import
|
|
|
|
|
|
the appropriate module. For example:</p>

<p>Each module except <code>common</code> corresponds to a system library. They all define a function named
|
|
|
|
|
|
<code>is_lib_available()</code> which returns a boolean depending on whether the lib could be loaded.
|
|
|
|
|
|
They always return true if the feature <code>dlopen</code> is absent, as the lib is then directly linked.</p>
