函数名: int86x

功 能: 通用8086软中断接口

用 法: int int86x(int intr_num, union REGS *insegs, union REGS *outregs,

struct SREGS *segregs);

程序例:

#include

#include

#include

int main(void)

{

char filename[80];

union REGS inregs, outregs;

struct SREGS segregs;

printf("Enter filename: ");

gets(filename);

inregs.h.ah = 0x43;

inregs.h.al = 0x21;

inregs.x.dx = FP_OFF(filename);

segregs.ds = FP_SEG(filename);

int86x(0x21, &inregs, &outregs, &segregs);

printf("File attribute: %X\", outregs.x.cx);

return 0;

}
