copy

Interface

static char_type* copy(char_type* s1, char_type const* s2, std::size_t n);

Pre-condition

s2 not in [s1,s1+n).

Effects

Equivalent to std::char_traits<Char>::copy(s1, s2, n).

Examples

#include <sprout/string.hpp>
#include <sprout/assert.hpp>
using namespace sprout;

char x[] = "homuhomu";
SPROUT_STATIC_CONSTEXPR char const* y = "madocchi";
int main() {
  char_traits<char>::copy(x, y, 8);
  SPROUT_ASSERT_MSG(x[0] == y[0], "y is copied to x.");
}

Complexity

linear.
