Global variable not updating

Flustration (1)
Hello! I am trying to find out why my global variables (textureBank, textureFree, numTextures) are not being updated from the texture object's constructor method texture(SDL_Surface *rawSurface). It is as if there is a local copy in that block, which appears to be updated inside the function, but outside of it retains its original value. I have tried this with and without the static keywords. Thanks!

//texture.cpp
#include "texture.h"
#include "iostream"

static GLuint textureBank[256];
static bool textureFree[256];
static int numTextures;

[CODE]void texture::generateTextureHandles()
{
    std::fill_n(textureFree, 256, true);
    glGenTextures( 256, textureBank);
}

    for(int a = 0; a < 256; a++)
    {
        std::cout << "texture # " << a << " status is " << textureFree[a];

        if(textureFree[a] == true)
        {

            glTexture = a;
            numTextures++;
            textureFree[a] = false;
            std::cout << " true, taking\n";
            break;
        }

Is textureBank, textureFree and numTextures only used inside texture.cpp?
