(C++) memmove

Syntax

void * memmove ( void * target, const void * source, size_t nBytes ); 

Example

include <cstdlib>

include <cassert>


int main()
{
  char one[] = "ONE"; //one cannot be const, as it will be memmoved over
  const char two[] = "TWO"; //two can be const as it will be copied from
  std::memmove(one,two,3); //copy content of two over one
  assert( std::memcmp(one,"TWO",3) == 0); //one will have the content "TWO"
  assert( std::memcmp(two,"TWO",3) == 0); //two will have the same content
}
