[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 04/10] libxl_json: Introduce libxl__json_object_to_yajl_gen.
This function converts a libxl__json_object to yajl by calling every yajl_gen_* function on a preallocated yajl_gen hand. This helps to integrate a json_object into an already existing yajl_gen tree. This function is used in a later patch.
