[Gambas-devel] Function Signature

[tommyline at ...674...]

Hi Randall,

Some time ago I was adding nurbs and quadrics to glu library, take a look at GLU.c, nurbscurve and nurbssurface, there is a semicolon after each array declaration.

Hope this helps.
Tomek.

Subject: [Gambas-devel] Function Signature


Hi, 

I am having trouble writing the proper function signature for a function that passes an array of floats. I have look ad the GL class of the OpenGl component as it seems to pass a lot of array as matrices. Something I will be doing shortly with Polynomials. 

I have the function: 

BEGIN_METHOD(GslPoly_Eval, GB_OBJECT array; GB_FLOAT x;) 

I have the following declaration in the class desc struct: 

GB_METHOD("Eval", "f", GSLPOLY_Eval, "(a)Float[](x)f") 

This does not work but if I swap the order of the arguments then it works. What am I missing and do you know of a good text on writing proper signatures for Gambas and/or C. 

Thanks again for your help!
