Function std.bitmanip.bigEndianToNative
Converts the given value from big endian to the native endianness and
returns it. The value is given as a ubyte[n]
where n
is the size
of the target type. You must give the target type as a template argument,
because there are multiple types with the same size and so the type of the
argument is not enough to determine the return type.
T bigEndianToNative(T, ulong n)
(
ubyte[n] val
) pure nothrow @nogc @safe
if (canSwapEndianness!T && (n == T .sizeof));
Taking a ubyte[n]
helps prevent accidentally using a swapped value
as a regular one (and in the case of floating point values, it's necessary,
because the FPU will mess up any swapped floating point values. So, you
can't actually have swapped floating point values as floating point values).
Example
ushort i = 12345;
ubyte[2] swappedI = nativeToBigEndian(i);
writeln(i); // bigEndianToNative!ushort(swappedI)
dchar c = 'D';
ubyte[4] swappedC = nativeToBigEndian(c);
writeln(c); // bigEndianToNative!dchar(swappedC)
