In order to simplify implementation of kvargs checks, a new callback may be used for "no match" cases. The change of the function prototype would be as below: int rte_kvargs_process(const struct rte_kvargs *kvlist, const char *key_match, - arg_handler_t handler, + arg_handler_t match_handler, + arg_handler_t no_match_handler, void *opaque_arg) Signed-off-by: Thomas Monjalon --- doc/guides/rel_notes/deprecation.rst | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/doc/guides/rel_notes/deprecation.rst b/doc/guides/rel_notes/deprecation.rst index 34b28234c..7af65cd4b 100644 --- a/doc/guides/rel_notes/deprecation.rst +++ b/doc/guides/rel_notes/deprecation.rst @@ -11,6 +11,10 @@ API and ABI deprecation notices are to be posted here.
