This method is a superset of <function>GetImageMetadata()</function> with the addition of
a list of extensions as input parameter, which were overlaid on top of the main
image via <function>AttachImageWithExtensions()</function>.
- The <varname>flag</varname> parameter is currently unused and reserved for future purposes.</para>
+ The <varname>flag</varname> parameter can be used to request that, before the units, the path of
+ each extension and an array of bytes with the content of the respective extension-release file
+ are sent. One such structure will be sent for each extension named in the input arguments. The
+ flag value to enable this functionality is defined as follows:</para>
+
+ <programlisting>
+#define PORTABLE_INSPECT_EXTENSION_RELEASES (UINT64_C(1) << 1)
+ </programlisting>
