truncate function not implemented in SPIFFS

[davdav]

Hello everybody,

truncate() function seems to be NOT implemented for spiffs components. If called, it returns -1
and errno is 88 which description in "\esp-idf\components\newlib\include\sys\errno.h" is

`#define ENOSYS 88 /* Function not implemented */`

Is it a problem of ESP-IDF or is it a problem of SPIFFS component itself?

I already opened an issue on github esp-idf repository.

Can someone confirm that?

Thanks
