Hi Folks,
I am trying to access FP_SEG and FP_OFF functions. Non of the DJPP's
header files have any reference to them. They are supposed to be in
dos.h. I wonder if I need to do something else. Here is a code that I am
trying to compile.
If someone can send some solution?
/************************/
union REGS inregs, outregs ;
struct SREGS segregs ;
unsigned char *fdata ;
fdata = (char *)profileptr ;
inregs.h.ah = 0x44 ; /* write ioctl command */
inregs.h.al = 0x03 ; /* write ioctl command */
inregs.x.bx = handle ; /* file handle */
segregs.ds = FP_SEG( fdata ) ;
inregs.x.dx = FP_OFF( fdata ) ;
inregs.x.cx = SETPROFILE ;
intdosx( &inregs, &outregs, &segregs ) ;
/ ****************************************/
