Dll's

Hello all,

I have a question about DLL's and wrappers. I'm currently putting together
a wrapper
for OpenGL. The question I have pertains to pointers and values that are
passed to
a function or procedure.

Let's suppose I come across a line in the C source that the DLL was made,
like:

WINGDIAPI void APIENTRY glColor3ui (GLuint red, GLuint green, GLuint blue);

This would translate to:

constant gl_Color3ui = define_c_proc(OpenGL, "glColor3ui",{C_INT,C_INT,C_INT})

Right?

But what if I run into this:

WINGDIAPI void APIENTRY glTexCoord1dv (const GLdouble *v);

Does it translate to:

constant gl_TexCoordldv = define_c_proc(OpenGL, "glTexCoordldv",{C_POINTER})

Does the "*" denote a pointer? If so, would there be any other instances where
I would need to use a pointer instead of passing or receiving a value
directly?

Also a question for Robert Craig. Are you going to ever install code into
Euphoria
that will allow for easier access to DLL's and possibly eliminate the need for
wrappers.

Thanks
Paul Martin
