Function miniextendr_register_routines 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn miniextendr_register_routines(
    dll: *mut DllInfo,
)

Register all #[miniextendr] routines and ALTREP classes with R.

Called from package_init() during R_init_* (via miniextendr_init!). Everything else is automatic.

Safety

Must be called from R’s main thread during R_init_*. dll must be a valid pointer provided by R.
