Some Win32 API types are different fundamental types in the 32-bit and 64-bit This problem is then further compounded by the fact that whilst both 32-bit Cygwin and 32-bit MinGW use the ILP32 data model, 64-bit MinGW uses the LLP64 data model, but 64-bit Cygwin uses the LP64 data model. This makes it impossible to write printf format specifiers which are correct for all those targets, so we use some macros to provide the correct specifier for the target. LPARAM and WPARAM are integer types which can contain a pointer LPARAM is long in ILP32 and long long in LLP64 WPARAM is unsigned int in ILP32 and unsigned long long in LLP64 Generally, these are just used to passs integer parameters, so for simplicity, cast to int and use an int-compatible format In the specific case of WM_CHANGECBCHAIN, they are used to pass HWND, so cast to that type and print using an appropriate format.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
