static char_type* move( char_type* dest, const char_type* src, std::size_t count );		(until C++20)
static constexpr char_type* move( char_type* dest, const char_type* src, std::size_t count );		(since C++20)

Copies count characters from the character string pointed to by src to the character string pointed to by dest.

Performs correctly even if the copied character ranges overlap, i.e. src is in [dest, dest + count).

Parameters

dest	-	pointer to a character string to copy to
src	-	pointer to a character string to copy from
count	-	the number of characters to copy

Return value

dest

Exceptions

Throws nothing.

Complexity

Linear.
