Add semantic patch to NULL the destroyed pointer early Our destroy functions usually look like this: void foo_destroy(foo_t *foop) { foo_t foo = foop; ...destroy the contents of foo... foop = NULL; } nulling the pointer should be done as soon as possible which is not always the case. This commit adds simple semantic patch that changes the example function to: void foo_destroy(foo_t foop) { foo_t foo = foop; *foop = NULL; ...destroy the contents of foo... } 2020-02-08 04:31:51 -08:00			`@@`
