`core.bitop.bswap` - multiple declarations

Function bswap

Swaps bytes in a 4 byte uint end-to-end, i.e. byte 0 becomes byte 3, byte 1 becomes byte 2, byte 2 becomes byte 1, byte 3 becomes byte 0.


						
				uint bswap
				(
				

				  uint v
				

				) pure nothrow @nogc @safe;

Example

writeln(bswap(0x01020304u)); // 0x04030201u
static uint xx = 0x10203040u;
writeln(bswap(xx)); // 0x40302010u

Function bswap

Swaps bytes in an 8 byte ulong end-to-end, i.e. byte 0 becomes byte 7, byte 1 becomes byte 6, etc. This is meant to be recognized by the compiler as an intrinsic.


						
				ulong bswap
				(
				

				  ulong v
				

				) pure nothrow @nogc @safe;

Example

writeln(bswap(0x01020304_05060708uL)); // 0x08070605_04030201uL
static ulong xx = 0x10203040_50607080uL;
writeln(bswap(xx)); // 0x80706050_40302010uL
