Why when I uncomment fseek line buf become empty?

What is open_memstream() ? It is not part of C89, and I've never
heard of it being part of C99.

fwrite("test", 1, 4, f);
// fseek(f, 0, SEEK_SET);
fclose(f);
fprintf(stderr, buf);
}

You appear to be using an implementation library function. You
will need to ask in a location that specializes in your implementation.
