I'm having the following DOS-code that I want to port 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 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;
}
How do i translate this? Can I just leave the 'far' out? And how do
I replace the FP_SEG and FP_OFF things?
Greetzzz,
mc303
