One valid and intended use of strncpy is to copy a C string to a fixed-length buffer while ensuring both that the buffer is not overflowed and that unused bytes in the target buffer are zeroed out perhaps to prevent information leaks if the buffer is to be written to media or transmitted to another process via an interprocess communication.</plaintext> ノート. strcpy_s は効率向上のためにコピー先配列の書き込まれた最後の文字から destsz までを上書きすることが許されています。 複数バイトのブロックをコピーしてからヌルのバイトをチェックするかもしれません。 関数 strcpy_s は BSD の関数 strlcpy と同様ですが、以下の点が異なります。. 10/02/2010 · Visual C Strcpy_s &Strcat_s Tutorial über die beiden befehle.
