Is there a better way to reverse an array of bytes in memory?

Question

typedef unsigned char Byte;

...

void ReverseBytes( void *start, int size )
{
    Byte *buffer = (Byte *)(start);

    for( int i = 0; i < size / 2; i++ ) {
             


        

Answer 1

The standard library has a std::reverse function:

#include 
void ReverseBytes( void *start, int size )
{
    char *istart = start, *iend = istart + size;
    std::reverse(istart, iend);
}
