I have been using targetcli to play around with LIO. I need to
configure the LIO targets, backstores, luns etc through c or c++

is easy but then you are invoking python from the c/c++ program and
have to parse the targetcli output. I am not thrilled about parsing
text output and i am not sure how granular it is (in terms of
configFS attributes). Also, it has python dependency. - use configFS
directly. That means, interact with the kernel drivers directly. It
gives more control but i am not sure how frequently configFS LIO
attributes change from one release to another and what is backward
compatibility? - i would prefer some c lib which i can link to. But i
didn't come across one yet
Yes I think you're right. There's a big opportunity for a person or
people to step up and make this happen. I'd hope that multiple
interested parties would contribute, so the workload was shared as much
as possible.
