Get address for an array element

Question

I'm developing a C program and I have a question about pointers and arrays.

I have the following array pointer:

GLuint *vboIds;

And the following function prototype:

void glGenBuffers(GLsizei n, GLuint *buffers);

The following statement is correct:

glGenBuffers(1, vboIds);

But I want to pass to glGenBuffers the second index of vboIds as second parameter for the function. I have put this:

glGenBuffers(1, &&vboIds[1]);

Is this correct?

Thanks.

Solution 1

glGenBuffers(1, &(vboIds[1]));

or what Armen said,

glGenBuffers(1, vboIds + 1);

Solution 2

Yes, it would be correct if you remove one ampersand.

You could also write glGenBuffers(1, vboIds + 1);.

Solution 3

glGenBuffers(1, vboIds + 1);
