The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml

<title>Description</title>
|
|
|
|
<para><function>sd_id128_randomize()</function> generates a new
|
|
randomized 128-bit ID and returns it in
|
|
<parameter>ret</parameter>. Every invocation returns a new
|
|
randomly generated ID. This uses the
|
|
<filename>/dev/urandom</filename> kernel random number
|
|
generator.</para>
|
|
|
|
<para>Note that <function>sd_id128_randomize()</function> always
|
|
returns a UUID v4-compatible ID.</para>
