Passing CGFloat array in core graphics

There are many functions in core graphics that take the pointer ie. pointer of array such as CGContextSetFillColor(context, colors);. I have to create the value for the array colors everytime and then pass the pointer to the function as;

CGFloat colors[] = {1.0, 0.0, 0., 1.0};
CGContextSetFillColor(context, colors);

But, it would be much easier if I could pass the values directly into the functions like;

CGContextSetFillColor(context, {1.0, 0.0, 0., 1.0});

The above syntax is not correct and the compiler complains about it, I have very limited understanding of how pointers work in C. So I would like to ask what is the correct way to pass the values directly in the same line.

According to the information from this answer on this question you can do this:

CGContextSetFillColor(context, (CGFloat[]){1.0, 0.0, 0., 1.0});
