libburn.h中struct burn_drive

在 libburn.h 中，struct burn_drive 是一个结构体，用于描述一个可写光盘驱动器的属性和状态。它包含了驱动器的一些基本信息，如驱动器的名称、类型、状态等，同时也包含了一些操作驱动器的函数指针，如读、写、检测、清除等。这个结构体的定义如下：

struct burn_drive {
  char *name;
  char *vendor;
  char *model;
  int type;
  int status;
  int media_status;
  int speed;
  int mmc_profile;
  int mmc_capabilities;
  int feature_set;
  int load_eject;
  int tray_open;
  int blank_state;
  int writable;
  int overwritable;
  int appendable;
  int reserve_track;
  int mcn_valid;
  char mcn[14];
  int isrc_valid;
  char isrc[13];
  int is_open;
  int fd;
  off_t capacity;
  struct burn_drive_info *info;
  struct burn_session_info *session_info;
  struct burn_track_info *track_info;
  struct burn_disc_info *disc_info;
  struct burn_write_opts *write_opts;
  struct burn_disc_cache *disc_cache;
  struct burn_source *source;
  struct burn_progress *progress;
  void *priv;
  int (*read)(struct burn_drive *, void *, size_t, off_t);
  int (*write)(struct burn_drive *, const void *, size_t, off_t);
  int (*check)(struct burn_drive *, off_t);
  int (*clear)(struct burn_drive *, off_t);
  int (*blank)(struct burn_drive *);
  int (*finalize)(struct burn_drive *);
  int (*eject)(struct burn_drive *);
  int (*load)(struct burn_drive *);
  int (*get_speed)(struct burn_drive *, int *);
  int (*set_speed)(struct burn_drive *, int);
  int (*get_status)(struct burn_drive *, int *);
  int (*get_media_status)(struct burn_drive *, int *);
  int (*get_capacity)(struct burn_drive *, off_t *);
  int (*lock_door)(struct burn_drive *);
  int (*query_format)(struct burn_drive *, const char *, int *);
  int (*set_write_opts)(struct burn_drive *, struct burn_write_opts *);
  int (*get_write_opts)(struct burn_drive *, struct burn_write_opts *);
};

这个结构体的具体用法可以参考libburn.h和libburn的相关文档。
