there api can use programatically talk device mapper: http://lwn.net/articles/35077/

this based around ioctl(), it's not friendliest, it's pretty documented: http://androidxref.com/4.4.4_r1/xref/bionic/libc/kernel/common/linux/dm-ioctl.h

there great example of use at: https://github.com/nelenkov/cryptsetup, albeit focussed on dm-verity.
