Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.

<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>

|
<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>
