+    <title>Description</title>
+
+    <para><function>udev_new()</function> allocates a new udev context
+    object and returns a pointer to it. This object is opaque and must
+    not be accessed by the caller via different means than functions
+    provided by libudev. Initially, the reference count of the context
+    is 1. You can acquire further references, and drop gained references
+    via <function>udev_ref()</function> and
+    <function>udev_unref()</function>. Once the reference count hits 0,
+    the context object is destroyed and freed.</para>

+    <title>Return Value</title>
+
+    <para>On success, <function>udev_new()</function> returns a pointer
+    to the allocated udev context. On failure, <constant>NULL</constant>
+    is returned. <function>udev_ref()</function> returns the argument
+    that it was passed, unmodified. <function>udev_unref()</function>
+    always returns <constant>NULL</constant>.</para>
