Question

I’m trying to write a class using soil to encapsulate SOIL calls. I can’t however find any other means of deleting the memory if I load the image using

SOIL_load_OGL_texture    

So what’s the correct way to clean up after this call?

Answer 1

It returns OGL texture identifier

/* load an image file directly as a new OpenGL texture */
GLuint tex_2d = SOIL_load_OGL_texture
    (
        "img.png",
        SOIL_LOAD_AUTO,
        SOIL_CREATE_NEW_ID,
        SOIL_FLAG_MIPMAPS | SOIL_FLAG_INVERT_Y | SOIL_FLAG_NTSC_SAFE_RGB | SOIL_FLAG_COMPRESS_TO_DXT
    );

so it should be freed using OGL functions:

glDeleteTextures( 1, &tex_2d );

I have not used this lib, but this is what I would do
