[tor/master] Let's have only one FREE_AND_NULL variant.

commit 95531ddfbfb6cb30760523d91fd4dfc966d2f6a5 Author: Nick Mathewson <nickm(a)torproject.org> Date: Thu Dec 7 10:37:59 2017 -0500 Let's have only one FREE_AND_NULL variant. This commit removes the old FREE_AND_NULL, and renames the old FREE_AND_NULL_UNMATCHED so that it is now called FREE_AND_NULL. This will break all the FREE_AND_NULL_* users; the next commit will fix them. --- src/common/util.h | 10 +--------- 1 file changed, 1 insertion(+), 9 deletions(-) diff --git a/src/common/util.h b/src/common/util.h index e85be57c0..97ad15f83 100644 --- a/src/common/util.h +++ b/src/common/util.h @@ -121,11 +121,8 @@ void tor_log_mallinfo(int severity); /* Helper macro: free a variable of type 'typename' using freefn, and * set the variable to NULL. - * - * We use this for legacy cases when freefn and typename don't line up - * perfectly. */ -#define FREE_AND_NULL_UNMATCHED(typename, freefn, var) \ +#define FREE_AND_NULL(typename, freefn, var) \ do { \ /* only evaluate (var) once. */ \ typename **tmp__free__ptr ## freefn = &(var); \ @@ -133,11 +130,6 @@ void tor_log_mallinfo(int severity); (*tmp__free__ptr ## freefn) = NULL; \ } while (0) -/* Helper macro: free a variable of type 'type' using type_free_, and - * set the variable to NULL. */ -#define FREE_AND_NULL(type, var) \ - FREE_AND_NULL_UNMATCHED(type ## _t, type ## _free_, (var)) - /** Macro: yield a pointer to the field at position off within the * structure st.
