Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
static char_type* copy(char_type* s1, char_type const* s2, std::size_t n);
|
|
|
|
Effects
|
|
========================================
|
|
|
|
| Equivalent to ``std::char_traits<Char>::copy(s1, s2, n)``.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/string.hpp>
|
|
#include <sprout/assert.hpp>
|
|
using namespace sprout;
|
|
|
|
char x[] = "homuhomu";
|
|
SPROUT_STATIC_CONSTEXPR char const* y = "madocchi";
|
|
char_traits<char>::copy(x, y, 8);
|
|
SPROUT_ASSERT_MSG(x[0] == y[0], "y is copied to x.");
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
| linear.
|
