GLINITNAMES(3G)

✨ NAME ✨

glInitNames — bestie, this is the one that resets your name stack to empty 💅

---

🎀 C SPECIFICATION 🎀

void glInitNames( void )

That's it. No args, no return value, no drama. She's a void queen. 👑

---

🌸 DESCRIPTION 🌸

okay so picture this: the name stack is what you use during selection mode, and its whole job is letting sets of rendering commands be uniquely identified. iykyk 🦋

It's made of an ordered set of unsigned integers, like a little lineup of IDs, one after another, in order, no cap.

What glInitNames does is cause that name stack to be initialized to its default empty state. poof. gone. fresh start. ✨

and here's the important bit: the name stack is always empty while the render mode is not GL_SELECT. so if you call glInitNames while the render mode isn't GL_SELECT, the call is just… ignored. literally ignored. she said nothing to me. 💀

💀 ERRORS 💀

• GL_INVALID_OPERATION is generated if glInitNames is executed between the execution of glBegin and the corresponding execution of glEnd.

so like, do NOT try to slide this in mid-glBegin/glEnd block, bestie. that's a hard no. 🚫
