In Wireshark/ui/qt/main_window.h there is a private member variable
defined as:
capture_file *cap_file_;
I think it's a pointer to the global variable "cfile" (defined in tshark.c).
Is it true that we keep this pointer only to verify the validity of
cfile (we set cap_file_ to NULL when the capture file is closed)?
