size_type copy( CharT* dest,                 size_type count,                 size_type pos = 0);

[pos, pos+count)が指す文字列に部分文字列destをコピーします。要求された部分文字列が文字列の終端を過ぎ、またはcount == nposあれば継続した場合、コピーされた部分文字列は、[pos, size())です。結果の文字列はNULLで終わるではない.

Original:

Copies a substring [pos, pos+count) to character string pointed to by dest. If the requested substring lasts past the end of the string, or if count == npos, the copied substring is [pos, size()). The resulting character string is not null-terminated.
