NAME

std::experimental::basic_string_view<CharT,Traits>::copy - std::experimental::basic_string_view<CharT,Traits>::copy

Synopsis


size_type copy( CharT* dest,
size_type count, (library fundamentals TS)
size_type pos = 0) const;


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().
