Checking texture existence

Original Post

If I use a texture, i.e. an unsigned integer (uint) to apply it to a polygon using glBindTexture(uint), can I know whether the texture pointed by uint exists in memory? Is there any method to check texture existence?

use glGetError > http://www.mevis.de/opengl/glGetError.html
beware, if you have others errors befors, better call
glGetError()// reset flags and ignore eventual previous errors
glBindTexture(...)
int err = glGetError()// real check

Calling glBindTexture with an unused texture ID is how you create new texture objects and is certainly not an error.
