若是指讓它推出或吸入的話..

#include <bios.h>
#include <dos.h>

void open(int driver,void *header);
typedef struct {
   char length;
   char subunicode;
   char commandcode;
   int status;
}rh;
typedef struct {
   rh r;
   char mdb;
   void far *address;
   int size;
   int ssn;
}ioctlo;
void main(void) {
   int drive=4;
   char opend=0;
   ioctlo o;
   o.r.length=13;
   o.r.subunicode=drive;
   o.r.commandcode=12;
   o.mdb=0;
   o.address=(void far*)&opend;
   o.size=1;
   open(drive,&o);
}
void open(int driver,void *header) {
   union REGS inregs;
   struct SREGS segregs;
   inregs.x.ax=0x1510;
   inregs.x.cx=driver;
   inregs.x.bx=FP_OFF(header);
   segregs.es=FP_SEG(header);
   int86x(0x2f,&inregs,&inregs,&segregs);
}
