Working around offsetof limitations in C++:

There is sometimes a situation in which one needs to get the relative offset of a structure field, common examples of this include serialization frameworks which aid to serialize objects, vertex attributes for rendering (D3D, GL.), etc.

The most common technique for getting this information is through the offsetof macro defined in stddef.h. Unfortunately using the macro in C++ comes with a new set of restrictions that prevent some (subjectively valid) uses of it.

sodu vim /etc/pf.anchors/com.liuxingruo

Inside the anchor file, enter:

rdr pass on lo0 inet proto tcp from any to self port 80 -> 127.0.0.1 port 9191
rdr pass on en0 inet proto tcp from any to any port 80 -> 127.0.0.1 port 9191
rdr pass on en1 inet proto tcp from any to any port 80 -&gt; 127.0.0.1 port 9191
