ESP8266 12E - How to use functions in SDK

[IOT_idlc]

Hello,
I used the AT commands of ESP8266 12e successfully. It's AT version is 0.4 & SDK version is 1.3. but i don't how to use the functions in SDK. I want to interface ESP8266 12E to my cortex 32bit controller through SPI communication & also i want to use the WiFi P2P functions in the SDK. I'm using windows 10 OS & LPC controllers & KEIL IDE. so can anybody tell me what are the basic requirements that i need so that i can build my application program in my controller. since I'm new to SDK's or API's. In CC3000 wifi module, through SPI interface we can call the wifi module functions through host controller. In the same way how can we use the SDK's function calls from my controller & how can i know what are the functions available in SDK's & how to access them from controller. Since there is no proper document available for my question.
