Summary
Added an early return in
ucl_strlcpy_unsafe()whensiz == 0.Fix
Added:
at the beginning of the function.
Why
The function assumes
sizis at least 1, but adding this check makes it safer if an invalid value is ever passed. It also avoids undefined behavior from usingsiz - 1.Compatibility
This change does not affect existing callers or valid inputs. It only adds a safe early return for the unexpected case where
sizis0.
