Okay, thanks. I'll experiment tomorrow evening. Cheers,--MGage--

Okey, so I see what they're trying to say, but what about functions from C that
actually take input? For example, in Cairo, cairo_move_to() would not make the
cut on its own. Matter of fact, it would take a surface in the form of a
pointer and an x and y value. So we would have
cairo_surface_t *crcairo_move_to(cr, x, y);
among countless others. Is Swift able to pull this out of thin air, or do we
have to take each individual function and convert it to Swift ourselves? I
guess what I'm asking is: Is Swift able to understand something like
import CCairofunc cairo_line_to: Void(let cairo_t = MutableUnsafePointer(cr),
x: Double, y: Double)
after I include just a header file and map it? The function draws a line on a
surface. Assuming the syntax is correct, then you're telling me the process is
just:
1) Map the cairo.h file to a system module named CCairo2) Include that in a
file3) Convert any functions you've entered in C into a Swift format, no
binding "workarounds" necessary like other lagnguages, and4) Swift recognizes
you meant to use that function that is written specifically in C and is
included in that header file mapped by CCairo. If Swift cannot automatically
know that you meant to pull a function from a C header file, what must I do if
it cannot?
I came here because I've read tutorials but am still confused on whether or not
the CCairo module itself can just recognize a function without having to do
more.

I read that. What I want to know is how to bind the functions
themselves after creating a system package. How to use the c functions that got
imported, if you will.

For any project: How is a C to Swift function binding
created? I'd like to know how to import C functions to Swift. Once I can do
this successfully, I'll be all set.
