Hey Guys

Does anyone know how to take a the first 4 bytes of a buffer and but it into a DWORD.

Cheers

Didn't we just do this?
Like two days ago....

an ansi c version

#define DWORD long

DWORD moveDW(char *t);
void main(void ){
   char *f = "hi there";
   printf("%d\n",moveDW(f) );
   return;
   }

DWORD moveDW(char *t){
     char *buf;
     int i;
     union u {
    unsigned char a[4];
    DWORD b;
    } m;
     buf = t;
     for(i=0;i<4;i++){
      m.a[i] = *buf;
      buf++;
     }
     return m.b;
}

Yeah except 2 days ago it was the other way round DWORD to Buffer.

DWORD a=*(DWORD*)buffer;
