『楼 主』:
[解决]求助！Turbo C 编译通过 连接出错~！
使用 LLM 解释/回答一下
请帮忙看看这是什么原因，连接时出现提示信息是这样的 ！
Linker Error: Undefined symbol `_inpw`in module HDS.C
谢谢了~！急死我了，知道上学的时候就不出去玩了~！
下边是原程序代码：
#include <stdlib.h>
#include <dos.h>
#include <stdio.h>
#include <conio.h>
#include <bios.h>
char *GetAscii(unsigned int inData, int offStart, int offEnd);
int main(void)
{
unsigned int diskData; /* Disk data */
unsigned int offset; /* Disk data offset */
int loop;
int numDrv; /* Number of IDE hard drives */
union REGS registers;
unsigned int biosCyl; /* Cylinders, Heads, Sectors */
unsigned int biosHead;
unsigned int biosSec ;
numDrv = peekb(0x40, 0x75); /* BIOS Data area, Number of Hard disks */
for (loop = 0; loop < numDrv; loop++)
{
while (inp(0x01f7) != 0x50); /* Wait for controller not busy */
outp(0x01f6, (loop == 0 ? 0xa0 : 0xb0)); /* Get first/second drive */
outp(0x01f7, 0xec); /* Get drive info data */
while (inp(0x1f7) != 0x58); /* Wait for data ready */
for (offset = 0; offset != 256; offset++) /* Read "sector" */
diskData = inpw(0x1f0);
/* Get BIOS drive info */
registers.h.ah = 0x08; /* Get drive info */
registers.h.dl = 0x80 + loop; /* Drive is 80H for Disk 0, 81H for Disk 1 */
int86(0x13, ®isters, ®isters);
if (!registers.x.cflag) /* All OK if carry not set */
{
biosHead = registers.h.dh + 1; /* Heads are from 0 */
biosSec = registers.h.cl & 0x3f; /* sec is bits 5 - 0 */
/* +1 because starts from 0 and +1 for FDISK leaving one out */
biosCyl = ((registers.h.cl & 0xc0) << 2) + registers.h.ch + 2;
} /* end of if */
printf("DRIVE %d:\n", loop);
printf("Model Number______________________: %s\n", GetAscii(diskData, 27, 46));
printf("Serial Number_____________________: %s\n", GetAscii(diskData, 10, 19));
printf("Controller Revision Number________: %s\n\n", GetAscii(diskData, 23, 26));
printf("Able to do Double Word Transfer___: %6s\n", (diskData == 0 ? "No" : "Yes"));
printf("Controller type___________________: %04X\n", diskData);
printf("Controller buffer size (bytes)____: %6u\n", diskData * 512);
printf("Number of ECC bytes transferred___: %6u\n", diskData);
printf("Number of sectors per interrupt___: %6u\n\n", diskData);
printf("Hard Disk Reports\n");
printf("Number of Cylinders (Fixed)_______: %6u\n", diskData);
printf("Number of Heads___________________: %6u\n", diskData);
printf("Number of Sectors per Track_______: %6u\n\n", diskData);
printf("BIOS Reports\n");
printf("Number of Cylinders_______________: %6u\n", biosCyl);
printf("Number of Heads___________________: %6u\n", biosHead);
printf("Number of Sectors per Track_______: %6u\n\n", biosSec);
} /* end of for */
return 0;
} /* main() */
char *GetAscii(unsigned int inData, int offStart, int offEnd)
{
static char retVal;
int loop, loop1;
for (loop = offStart, loop1 = 0; loop <= offEnd; loop++)
{
retVal = (char )(inData / 256); /* Get High byte */
retVal = (char )(inData % 256); /* Get Low byte */
} /* end of for */
retVal = '\0'; /* Make sure it ends in a NULL character */
return retVal;
} /* GetAscii() */
谢谢大家，问题以经解决了，此源码须用BORLAND C++ 6.0编译才能通过~！
