Question

Well, I think I am having issues with resolving two functions with the same name and I do not know how to resolve it.

I have a Qt class which is a subclass of QDialog (Qt). I would like to use ‘fstat’ to get information about the file using a code like below

struct stat file_info;
int hd = open("/home/test/file.xml", O_RDONLY);
fstat(hd, &file_info);
close(hd);

But when I do this, I get this complain from the compiler.

error: no matching function for call to 'Test::open(const char [19], int)'
/usr/local/Trolltech/Qt-4.7.3/include/QtGui/qdialog.h::99:10: note: candidate is: void QDialog::open()

Is there some way to resolve this?

Thanks.

Answer:

As Caladan mentions, ::open() did the trick. Also the second answer (to use stat instead of fstat) was equally valid. Thanks!

Answer 1

You can try calling ::open() which will hint the compiler it should not look in the current scope.

You can also use stat() which just gets the file name instead of a descriptor.
