API SDK functions. I search for those functions to see how they are defined but I couldn't find them in any folders inside esp-open-sdk (crosstool-NG, esp_iot_Sdk_v1.5.2, esptool, examp[les, lx106-hal, esp-open-lwip, sdk, xtensa-lx106-elf)
I search inside of those folders but I couldn't find those API SDK functions listed above.

So, where are they located?
