Question

The android NDK is complaining about this:

#include <stdio.h>
int fileno (FILE *stream); //line 27 io.h

It says:

jni/application/io.h:27:5: error: expected ')' before '*' token
jni/application/io.h:27:5: error: expected ')' before '->' token

I would understand if FILE was some macro, but it’s not, it’s just the one from stdio.

If I take out the *stream I get:

int fileno (FILE);
jni/application/io.h:27:5: error: expected ')' before '->' token

I can’t understand where it’s getting the -> token from.

Answer 1

Wait I see, fileno is macro in stdio.h

So was expanding to:

int ((FILE* stream)->_file);
