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.
