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.

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).

Prototype

T bigEndianToNative(T, ulong n)(
  ubyte[n] val
) pure nothrow @nogc @safe
if (canSwapEndianness!T && n == T.sizeof);

Example

ushort i = 12345;
ubyte[2] swappedI = nativeToBigEndian(i);
assert(i == bigEndianToNative!ushort(swappedI));

dchar c = 'D';
ubyte[4] swappedC = nativeToBigEndian(c);
assert(c == bigEndianToNative!dchar(swappedC));
