EAP TLS - Hostapd

[Satya Prakash Prasad]

Hi,

Referring to https://github.com/prplfoundation/hostap/tree/master -
please guide me code example - how after authentication successful
read / write data exchange will happen.

I was referring to below peer example code:

https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_example_peer.c

After the EAP success case, how peer / server side will read / write
data - which APIs code implements the same - also how do we verify
that EAP authentication was successful before each write / data?
