[gameprogrammer] Re: is safe this?

yes that is safe (:

the reason why is GLuint is just a "number" type (ie 1,2,3,4...or 1000 etc).

so when you call glGenTexture it's creating a texture in video memory
and then creating a unique ID# for that texture and storing that ID#
in tmp.

When you return that from the function it's just returning the ID# (handle).

When you return tmp, you are'nt returning the image data itself to the
calling function, you are just returning the unique ID # of the image
data.

If I remember right, that image data will stay in video memory until
either your program ends, or until you tell gl to destroy that
texture.

Is safe to create a GL texture and return it as function result?
Im thinking to implement an image loading and conversion function like this:

GLuint load(char *file)
{
 GLuint tmp
 load image ***
 glGenTexture(1,&tmp)
 convert surface to texture

 return tmp

}

But Im not sure if the returned value can be safely used as a texture.
