size_type copy( CharT* dest,

                size_type count,

                size_type pos = 0) const;
(library fundamentals TS)

Copies the substring [pos, pos + rcount) to the character string pointed to by dest, where rcount is the smaller of count and size() - pos.

Parameters

dest - pointer to the destination character string
pos - position of the first character
count - requested substring length

Return value

Number of characters copied

Exceptions

std::out_of_range if pos > size().

Complexity

Linear in rcount.
