C question (linux)

Does anyone have any suggestions as to why this:

int file_open(char *name, int mode)
{

//	return open(name, mode);

        return fopen(name, "r");
}

Would return the following when compiled:

warning: return makes integer from pointer without a cast


This is driving me absolutely mad! I'm attempting to adjust the source of a 
program I didn't write. For whatever reason, the old open() call is returning 
an invalid file descriptor (134758848 to be exact) so I am trying to change 
it from open() to fopen(). The files passed through this routine are all read 
only types, so there is no reason for mode to ever be anything but 0 ("r") so 
I figured just change the ,mode) to a "r"

If anyone could think of any reason why I would get that message. I have no 
idea why, but I keep coming up with it.

Thanks!
