Query: Any MACRO can be used in code to distuigush major SO version 4 and Majsor SO version 3?

[starx1000]

hello,
New libnetconf2 introduced new API e.g

nc_client_ssh_set_knownhosts_mode

and obsolete some API e.g

nc_client_ssh_set_auth_hostkey_check_clb

Changed some API, e.g
from void nc_client_init() to int nc_client_init()

Is there any MACRO can be used then we can compile the code and use it with different version?

For example OPENSSL:

#if OPENSSL_VERSION_NUMBER < 0x30000000L
    CallSomeAPIOnlyAvaibleLessThanThirdZero()
#else
    CallSomeAPIOnlyAvaibleBigThanThirdZero()
#endif

Thank you.

Then I can write some code like e.g

#if LIBNETCONF2_VERSION_NUMBER < 0x400L
    nc_client_ssh_set_auth_hostkey_check_clb();
#else
   nc_client_ssh_set_knownhosts_mode();
#endif

There is the header nc_version.h that you can include manually and then test for NC_VERSION_MAJOR. But I think the differences are significant so I am not sure what code you will end up with when trying to support both version in a single project.

OK, got it. thank you.

I only used part of the client and all those 3 changes is what I seen from the changes.

nc_client_ssh_set_auth_hostkey_check_clb
nc_client_ssh_set_knownhosts_mode
int nc_client_init()

Other API that I used here includes:

nc_connect_ssh
nc_client_ssh_set_auth_password_clb
nc_client_ssh_set_username
nc_client_destroy

nc_session_free
nc_session_get_status

nc_send_rpc
nc_recv_reply
nc_recv_notif

nc_rpc_establishsub
nc_rpc_free
nc_rpc_getdata
nc_rpc_editdata

Looks like no changes for those APIs? Or do you see any changes inside between the APIs?

If you are using only the client API then yes, you should be fine.
