How do I translate the following piece of DOS-code to linux?

static union {
  unsigned int *a;      // One 32 bits address
  unsigned long  l;     // One 32 bits long
  unsigned int w[2];    // Two 16 bits words
  unsigned char  b[4];  // Four 8 bits bytes
} DMAaddr;

static union {
  signed int w;         // One 16 bits words
  signed char  b[2];    // Two 8 bits bytes
} DMAcntr;

...

static void setadr( unsigned int far *buff, unsigned int length )
{
  unsigned int lw;

  lw = FP_SEG( buff );                // Segment address of buffer
  DMAaddr.w[1] = ( lw >> 12 ) & 0xf;    // Makes real 32bit address
  DMAaddr.w[0] = ( lw << 4 ) & 0xfff0;
  DMAaddr.l += ( unsigned long )FP_OFF( buff );
  DMAcntr.w = length;
}


Thanks,
