<para>
Creates a copy of the current path and returns it to the user as a <classname>CairoPath</classname>.
See <classname>CairoPath</classname> for hints on how to iterate over the returned data structure.
</para>
<para>
This function will always return a valid <classname>CairoPath</classname> object,
but the result will have no data, if either of the following conditions hold:
<simplelist>
<member>1. If there is insufficient memory to copy the path. In this case CairoPath->status will
be set to CAIRO_STATUS_NO_MEMORY.</member>
<member>2. If <parameter>context</parameter> is already in an error state.
In this case CairoPath->status will contain the same status that would be returned by
<function>cairo_status</function>.</member>
</simplelist>
In either case, CairoPath->status will be set to CAIRO_STATUS_NO_MEMORY
(regardless of what the error status in cr might have been).
