c - c中的remove()函数给出错误？

Question

以下函数获取一个名称并从名为 All.bin 的二进制文件中删除该名称。据我所知，它工作正常，但删除功能总是给出错误

 void del(char *name)
    {
        struct database d; //strucutre variable containing name and meaning
        FILE *p, *q;
        p = fopen("All.bin","r"); //original file
        q = fopen("temp.bin","w"); // temp file
        while(fread(&d,sizeof(d),1,p))
            if(strcmp(d.name,name) != 0)
                fwrite(&d,sizeof(d),1,q);
        fclose(p);
        fclose(q);
        if(remove("All.bin")!=0) //PROBLEM
            printf("Error");
        if(rename("temp.bin","All.bin")!=0)
            printf("Error@");
        getch();
    }

Answer 1

这对我来说效果很好。创建 All.bin 文件后更改文件权限
