About glBindTextureEXT, glGenTexturesEXT, glDeleteTexturesEXT & glAddSwapHintRectWIN

I have found many applications that can deal with large numbers of textures always call glBindTextureEXT, glGenTexturesEXT, glDeleteTexturesEXT & glAddSwapHintRectWIN. I can not find any information on them. Please give me some idea on how to use them.


About glBindTextureEXT, glGenTexturesEXT, glDeleteTexturesEXT:

I guess these applications are very old, and was written for OpenGL 1.0 (when texture objects was available only with GL_EXT_texture_object). But OpenGL 1.0 is gone by now, and texture objects was included in the core.
You have to change these functions on glBindTexture, glGenTextures and glDeleteTextures respectively.
