where are esp_wifi.c ,esp_mesh.c files means where are the esp_wifi_init() function written? in idf which file?

Anyone ??

esp_wifi_init.c is defined in components/esp_wifi/src/wifi_init.c . Note that this is part of the WiFi driver which is partially closed source, so of some of the functions this function calls, not all sources are available.

Thanks a lot there are many functions that are not available is there any function that can broadcast message and read the broadcast message.

Sure, probably, but you'll have to be a bit more clear than that... you have ESP-Now, UDP broadcast messages, mesh-like solutions which can do broadcasts via propagation, ...
