We have flags in the existing output functions:
int nft_table_snprintf(char *buf, size_t size, struct nft_table *t,
uint32_t type, uint32_t flags);
int nft_table_fprintf(FILE *fp, struct nft_table *t, uint32_t type,
uint32_t flags);
I think you can add a new flag that tells that you have to add the
extra event handling that you need, thus, we don't need a new
interface.
You can most likely reuse most of the code in this patch.
