I think there may have been some miscommunication. There is no
need to declare the pointer to your struct as global.

There's a BIG difference, called "modularity". Global variables
should be avoided at all costs. Read chapter 18 of your "Practical C
Programming" book. Also, download a few (mature) Open Source projects and
examine the structure of their codebase.
Also, whether or not your structure is global, the function is
expecting a pointer, NOT a structure (of ANY type), so you MUST pass the
function a pointer and reference the variables like
the_struct->member
...which is something you should get used to as soon as possible
anyhow. Much of Gtk+ (and any other well-designed library) is designed to
work that way.
