使用libparted库写个程序来打印我们的设备信息（2）

这一节我们将设备的分区打印出来。

 

代码如下：

#include <parted/parted.h>#include <stdio.h>int main(int argc, char* argv[]){ped_device_probe_all();PedDevice *dev = 0;while((dev = ped_device_get_next(dev))){printf("/n ==============================================/n");printf("device model: %s/n", dev->model);printf("path: %s/n",dev->path);long long size = (dev->sector_size * dev->length)/(1024*1024*1024);printf("size: %lld G/n", size);PedDisk* disk = ped_disk_new(dev);PedPartition* part = 0;while((part = ped_disk_next_partition(disk, part))){//略过不是分区的空间if ((part->type & PED_PARTITION_METADATA) ||(part->type & PED_PARTITION_FREESPACE) ||(part->type & PED_PARTITION_EXTENDED))continue;printf("++++++++++++++++++++++++++++++++++++/n");printf("partition: %s/n", ped_partition_get_path(part));if(part->fs_type)printf("fs_type: %s/n", part->fs_type->name);elseprintf("fs_type: (null)/n");//printf("partition start:%lld/n", part->geom.start);//printf("partition end: %lld/n", part->geom.end);printf("partition length:%lld M/n", (part->geom.length * dev->sector_size)/(1024*1024));}}return 0;}

编译：gcc -g -Wall -lparted main.c

运行：sudo ./a.out

运行结果（部分截图）：
