how to allocate a new node in binary tree using POBJ_NEW or PBJ_ALLOC

[Supriya Mishra SVNIT]

Hi everyone,

I am trying to write a recursive algorithm to insert a new node to a PM based binary tree data structure. After traversing we get the right location to insert new node. but how to allocate memory for new node using libpmemobj library.

Can anybody help?

Best regards,

Supriya

Hello,

There are a few examples in libpmemobj and libpmemobj-cpp library that shows how to implement a persistent data structure:
https://github.com/pmem/pmdk/tree/master/src/examples/libpmemobj
https://github.com/pmem/libpmemobj-cpp/tree/master/examples

Specifically, I would recommend taking a look at the following, rather simple one:

Best regards,
Igor
