Another good use is probably calling the initialization functions of some library, a bunch of which needs to be called in each program. You can make a separate file with the constructor files calling properly the library functions (probably operating on globals) and calling the library cleanup fu...

Specifically, the context information is useful when the front end issues a diagnostic while doing a template instantiation or while generating a constructor, destructor, or assignment operator function. For example: "test.c", line 7: error: "A::A()" is inaccessible B x; ^ detected during ...

-fno-elide-constructors The C++ standard allows an implementation to omit creating a temporary that is only used to initialize another object of the same type. Specifying this option disables that optimization, and forces G++ to call the copy constructor in all cases. This option also causes ...

Here is a simple example of a POINT structure, which contains two integers named x and y, and also shows how to initialize a structure in the constructor: from ctypes import * class POINT(Structure): ...fields= [("x", c_int), ...
