Hello,

I'm writing the bindings to a C library which uses, in some functions, global variables.

To make it clearer, those functions need a global variable to be defined. A C program using my_function, one of the library functions, would look like:

I don't think you can use the FFI to declare symbols for C. One not-so-pretty but effective way to do it is create a stub.c with the variables declared along with setting functions, then bind those functions like any other.
