long ftell(FILE *stream);

int fprintf(FILE *stream,
            const char *format,
            ...);

int fscanf(FILE *stream,
           const char *format,
           ...);

## Buffer Overflow

size_t fread(void *ptr,
             size_t size,
             size_t nmemb,
             FILE *stream);

size_t fwrite(const void *ptr,
              size_t size,
              size_t nmemb,
              FILE *stream);
