Convert F_FILE * to FILE * or file descriptor?

[Heliotopos]

Is it possible to convert the F_FILE * returned by the EFFS f_open() function to a FILE * or file descriptor? I'd like to use either vfprintf() with the former or ReplaceStdio() with the latter to print to my files.

Hi Heliotopos,

Unfortunately, a conversion like that isn't really an option. If you're looking to use the vfprintf() functionality with regard to format specifiers, there is an equivalent function available that's provided with our EFFS libraries, f_fprintf().

The signature is:

f_fprintf(F_FILE* fp, const char *format, ... );

Its usage can be found throughout our EFFS examples.

Kind Regards,
Jon

Exactly what I was looking for, thanks!
