cairo_copy_path.RdCreates a copy of the current path and returns it to the user as a #cairo_path_t. See #cairo_path_data_t for hints on how to iterate over the returned data structure.
cairo_copy_path(cr)
| cr | [ |

[cairo_path_t *]
This function will always return a valid pointer, but the result will have no data (<literal>data==%NULL</literal> and <literal>num_data==0</literal>), if either of the following conditions hold:
<orderedlist> <listitem>If there is insufficient memory to copy the path. In this case <literal>path->status</literal> will be set to %CAIRO_STATUS_NO_MEMORY.</listitem> <listitem>If cr is already in an error state. In this case <literal>path->status</literal> will contain the same status that would be returned by cairo_status().</listitem> </orderedlist>
Return value: the copy of the current path. The caller owns the returned object and should call cairo_path_destroy() when finished with it.
