+Subject: [PATCH] define and use type-safe callbacks
+
+fixes build errors with c23 and gcc-15
+
+    error: too many arguments to function 'h->destructor'; expected 0, have 1
+    error: passing argument 4 of 'lgHdlAlloc' from incompatible pointer type
+      [-Wincompatible-pointer-types]
+    note: expected 'callbk_t' {aka 'void (*)(void)'} but argument is of type 'void (*)(struct <anonymous> *)'
+    error: too many arguments to function 'lgGpioSamplesFunc'; expected 0, have 3
+    error: assignment to 'callbk_t' {aka 'void (*)(void)'} from incompatible pointer type 'lgGpioAlertsFunc_t' {aka 'void (*)(int,  struct lgGpioAlert_s *, void *)'}
+    note: 'callbk_t' declared here
+      377 | typedef void (*callbk_t) ();
