Answer

You can use df command. This will display something like that:

# df -h
Filesystem Size Used Available Use% Mounted on
tmpfs 46.9M 0 46.9M 0% /dev
tmpfs 4.0M 0 4.0M 0% /sqlite_stmt_journals
/dev/block/mtdblock1 87.5M 87.5M 0 100% /system
/dev/block/mtdblock2 1.3M 1.1M 120.0k 91% /userdata
/dev/block/mmcblk0p1 944.9M 130.4M 804.9M 14% /data
/dev/block/mtdblock5 35.8M 1.6M 34.2M 4% /dbdata
/dev/block/mtdblock4 87.5M 4.9M 82.6M 6% /cache
/dev/block/vold/180:2
6.6G 2.7G 3.8G 41% /sdcard
/dev/block/vold/179:9
7.6G 1.5G 6.1G 19% /sdcard/sd

The second option would be to read the /proc/self/mountinfo file.
