Is it possible to input an array into a .effect file? How does gs_effect_set_val work?

[ac2522]

If I have uniform float2 points[26];, is there any way to initialize these values?
points_cpp is a vec2[26] within my c++.

gs_effect_set_val(pointsParam, points_cpp, sizeof(points_cpp));
error: Parameter 'points' set to invalid size 208, expected 8

gs_effect_set_vec2(pointsParam, points_cpp)
error: gs_shader_set_val (GL): Size of shader param does not match the size of the input

for (size_t i = 0; i < 26; ++i) {
    point_param = gs_effect_get_param_by_name(tf->shaderEffect, ("points[" + std::to_string(i) + "]").c_str());
    const vec2 point = {points_cpp[i].x, points_cpp[i].y};
    gs_effect_set_vec2(point_param, &point);
}

error: effect_setval_inline: invalid param

Maybe I've missed something, but I can't find a way to input an array, so i'm left to mannually input 26 different points. Which seems a little inefficient, especially if I want to iterate over them within the shader...

I've tried to look for examples of working ".effect" shader files, that use arrays, but the best I could finrd was a commented array:

// Settings (Private)
//uniform float registerkernel[25];

Any help would be greatfully appreciated! I relaize there's a high chance I overlooked something completely obvious....
