I would prefer this option as it provides more flexibility. We can leave the existing API as is and a wrapper that accepts additional parameters. Something like the following (with implementations in the .c obviously rather than inline the header like I have it here). There are several examples of this pattern already in the dpdk (i.e., ring APIs, mempool APIs, etc.) where we use a common function invoked by higher level functions that pass in additional parameters to customize behavior.
struct rte_cfgfile *_rte_cfgfile_load(const char *filename,
const struct rte_cfgfile_params *params);
struct rte_cfgfile *rte_cfgfile_load(const char *filename, int flags)
{
struct rte_cfgfile_params params;
rte_cfgfile_set_default_params(¶ms);
params |= flags;
return _rte_cfgfile_load(filename, ¶ms);
}
struct rte_cfgfile *rte_cfgfile_load_with_params(const char *filename,
const struct rte_cfgfile_params *params)
{
return _rte_cfgfile_load(filename, params);
}
