[#lv_deprecated] ```c title=" " lineNumbers=1 #define LV_DEPRECATED(msg) ``` Mark a function as deprecated so the compiler emits a warning at every call site.

Works by declaring a local typedef tagged as deprecated and immediately using it, which triggers the warning without any runtime overhead. Example: ```c title=" " lineNumbers=1 #define MY_OLD_MACRO(x) \ do { LV_DEPRECATED_MACRO_WARN("MY_OLD_MACRO is deprecated, use MY_NEW_MACRO"); \ (x); } while(0) ``` Dependencies [#dependencies]
