nothrow char[] xarraydup(const(char)[] s);
Makes a null-terminated copy of the given string on newly allocated memory. The null-terminator won't be part of the returned string slice. It will be at position n where n is the length of the input string.
const(char)[] s string to copy
A null-terminated copy of the input array.
auto s1 = "foo";
auto s2 = s1.xarraydup;
s2[0] = 'b';
assert(s1 == "foo");
assert(s2 == "boo");
assert(*(s2.ptr + s2.length) == '\0');
string sEmpty;
assert(sEmpty.xarraydup is null);
nothrow T[] arraydup(T)(scope const T[] s);
Makes a copy of the given array on newly allocated memory.
T[] s array to copy
A copy of the input array.
auto s1 = [0, 1, 2];
auto s2 = s1.arraydup;
s2[0] = 4;
assert(s1 == [0, 1, 2]);
assert(s2 == [4, 1, 2]);
string sEmpty;
assert(sEmpty.arraydup is null);
