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>

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).
