const CharT* c_str()const; | ||
文字列内に格納されているものと同等のデータを持つNULLで終わる文字配列へのポインタを返します。ポインタが範囲
[c_str(); c_str() + size()]が有効であり、その中の値は、最後の位置の後に追加のNULL文字を含む文字列に格納された値に対応するようです.Original:
Returns a pointer to a null-terminated character array with data equivalent to those stored in the string. The pointer is such that the range
[c_str(); c_str() + size()] is valid and the values in it correspond to the values stored in the string with an additional null character after the last position.The text has been machine-translated via Google Translate.
