This is sdrawkcab.
In the .H file:
extern int my_variable;
In one -- and only one -- of the .C or .CPP files:
int my_variable;
The first tells everyone that there will be an variable
with the name "my_variable" available for use, but
does not allocate any memory for the value. The
keyword "extern" is a msg to the compiler that says
"don't worry about it, it's the linker's job".
The second actually allocates the storage for
"my_variable". This must be done once only!
The linker will then match up this allocated memory
with all uses of "my_variable" in the other modules.
