c - 在 C 中从文件中读取逗号分隔值

Question

我想读这个

                zeyad,aar,eee,100,sss,55,science
                toto,art,bb,100,ss,55,drawing

从文件中获取，然后将其存储在 books.title、books.publisher 等结构中，如下所示

有人可以告诉我如何不读取逗号并仅将字符串存储在其位置吗？我尝试在每个字符串之间使用 %*C 但它不起作用。

while (!feof(pBook))
{
    fscanf(pBook,"%s%*c%s%*c%s%*c%s%*c%s%*c%d%*c%s",
        books[z].Title,books[z].Author,books[z].Publisher,books[z].ISBN,books[z].DOP,
        &books[z].Copies,books[z].Category);
    fscanf(pBook,"\n");
    z++;
}
fclose(pBook);

一个简单的例子(未经测试):

void SeparateCommas(char *FileName)
{
 FILE *fd = fopen(FileName, "r");
 size_t len = 0;
 ssize_t read;
 char *line = NULL;
 char temp[50][32];
 char *token;
 char *end_str;

 while((read = getline(&line, &len, fd)) != -1)
    {
     printf("Read line: %s", line);
     token = strtok_r(line, ",", &end_str);

     while(token != NULL)
         {
          strncpy(temp[i], token, sizeof(temp[i]));
          printf("Read word: %s", temp[i]);
          token = strtok_r(NULL, ",", &end_str);
          i++;
         }
    }       
}
