Here is the full gcc output when building as C++11:
test.cpp: In function 'int main()':
test.cpp:5:4: error: '_fileno' was not declared in this scope
_fileno( f );
^~~~~~~
test.cpp:5:4: note: suggested alternative: '_filbuf'
_fileno( f );
^~~~~~~
_filbuf
According to:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/fileno
_fileno() shall be declared in stdio.h .
