Works, but not exactly elegant, and definitely not efficient. You'd be better off using the existing liblvm2cmd library. This gives you a programmatic interface to the command line toolset. It will still mean formatting commandlines/parsing returns but it cuts down on your forking and allows the library to cache LVM2 internal data across command invocations - potentially, that amounts to a big saving. See doc/example_cmdlib.c in the LVM2 sources for a short example program. > * delve deeply into the LVM utilities source code to find the ioctl calls > and/or procfs+sysfs structures being used, then duplicate this in my own > work. Not a good idea - there's too much complexity involved and duplicating that in separate projects would lead to something pretty unmaintainable quite quickly. > * use a premade LVM interface library. There is work in progress to create this kind of interface.
