FUSE錯誤：傳輸端點未連接

我試圖實現FUSE文件系統。我收到此錯誤：FUSE錯誤：傳輸端點未連接

cannot access MountDir: Transport endpoint is not connected

這是程序的相關部分。有兩個目錄，MirrorDir和MountDir，與所有代碼存在相同的目錄。我打電話給這樣的程序：

./myFS -o nonempty -o allow_other MirrorDir MountDir

任何人都可以看到我在做什麼錯？

static struct fuse_operations xmp_oper = { 
    .getattr = xmp_getattr, 
    .readdir = xmp_readdir, 
    .open  = xmp_open, 
    .read  = xmp_read, 
}; 

int main(int argc, char *argv[]) { 
    int fuse_stat; 
    char* mirrorDir; 

    mirrorDir = malloc(sizeof(strlen(argv[argc-2]+1))); 
    if (mirrorDir == NULL) { 
     perror("main calloc"); 
     abort(); 
    } 

    // Pull the rootdir out of the argument list and save it in my internal data 
    mirrorDir = realpath(argv[argc-2], NULL); 

    argv[argc-2] = argv[argc-1]; 
    argv[argc-1] = NULL; 
    argc--; 

    // turn over control to fuse 
    fprintf(stderr, "about to call fuse_main\n"); 
    fuse_stat = fuse_main(argc, argv, &xmp_oper, mirrorDir); 
    fprintf(stderr, "fuse_main returned %d\n", fuse_stat); 
    return fuse_stat; 
}
