Does wiced_hostname_lookup() work for you?
Or LwIP supports getaddrinfo() as lwip_getaddrinfo().
Sure, That seems a close function to linux's getaddrinfo. Can you tell me if I need to add this library(LWIP) explicitly in my project? if so, which directory? or an include of header would be ok, if this library is present in WICED SDK?
wiced_hostname_lookup() is prepared as a part of normal WICED API.
So you can call it in your application.
LwIP is not used as default.
Adding -FreeRTOS-LwIP like below builds your application with LwIP.
Please refer <WICED-SDK>/Makefile for detail
