[C語言]讀取txt檔案內容輸出bin file

手邊有個txt檔案,檔案內容如下

00 FF FF FF FF FF FF 00 4C 2D 1B 0D 45 4D 5A 5A
29 1A 01 03 0E 30 1B 78 2A 4A 05 A2 5A 52 A1 27
0D 50 54 BF EF 80 71 4F 81 C0 81 00 81 80 95 00
A9 C0 B3 00 01 01 02 3A 80 18 71 38 2D 40 58 2C
45 00 DD 0C 11 00 00 1E 00 00 00 FD 00 38 4B 1E
51 11 00 0A 20 20 20 20 20 20 00 00 00 FC 00 53
32 32 46 33 35 30 0A 20 20 20 20 20 00 00 00 FF
00 48 34 5A 48 41 30 30 30 39 36 0A 20 20 01 EB

我想把txt內容轉換成*.bin file

1. 開發環境 : DEV C++

2. 程式碼

#include <stdio.h>
#include <stdlib.h>
#include <string.h> 

size_t ReadTxtFile(FILE *inf, unsigned char *dest, FILE *outfile) 
{
    size_t count = 0;
    int n;
    unsigned char OneByte;
    
    if (dest == NULL) 
    {  
        //讀取txt檔案內容,轉成16進制.直到讀取結束     
        while ((n = fscanf(inf, "%hhx", &OneByte)) == 1 ) 
        {
          //printf("@@ %x\n",OneByte);
          //把讀取出來的資料寫入bin檔  
          fwrite(&OneByte, sizeof(unsigned char), 1, outfile);
          count++;
        }
    }
  
    if (n != EOF) 
    {
        ;  // handle syntax error
    }
    
    //printf("count=%d\n",count);
    return count;
}

int main() 
{
    //讀取txt檔案,檔案一定要放在跟目錄下不然會找不到 
    FILE *FileIn = fopen("d:\\21.txt", "rt");
    //如果檔案為空return fail 
    if (!FileIn) 
    {
        fclose(FileIn);
        return -1;
    }
    
    //創建一個bin檔 
    FILE* FileOut = fopen("d:\\fileOut.bin","wb+");
    //如果檔案為空return fail
    if (!FileOut) 
    {
        fclose(FileOut);
        return -1;
    }
    
    //轉換檔案 
    size_t n = ReadTxtFile(FileIn, NULL, FileOut);
    
    //把指標指向檔案頭 
    rewind(FileIn);
  
    //關閉檔案 
    fclose(FileIn);
    fclose(FileOut);
    
    system("PAUSE");
    return 0;
 }
