effect. Replace calls by struct assignment where possible. Replace clear buffer, copy string to buffer by strncpy(). Use assignment to clear when that's clearer. Replace overlapping copy through bounce buffer by memmove(). Replace rest by standard memset() and memcpy(). Also use sizeof() instead of literal array sizes for robustness, and instead of symbolic array sizes for clarity.
