what does fopen do on ESP32?

[timl12332]

Hi

Since the ESP32 doesn't have a harddrive in the way a pc does, what happens when I call fopen?(if it does anything?)
Will it create a file in SPIFFS?
Is there a way to make it work, as I can't get it to work.(Gives me an error when trying to create a file)
It would be nice if I can use the FILE class as pretty much every library uses it.(e.g. stb_image)

Thx!

Maybe you should read some documentation.
Virtual filesystem component
FAT Filesystem Support
SPIFFS Filesystem
And try some examples.
Wear levelling example
SD Card example
SPIFFS example
