GLDELETELISTS(3G)

✨ GLDELETELISTS ✨

okay bestie, welcome to glDeleteLists — that's the 3G manual page, GL family, the one that does the deleting 💅. Yeah. She's the cleanup crew. Let's get into it 🎀

---

💖 NAME 💖

glDeleteLists — delete a contiguous group of display lists 🗑️✨

No cap, that's the whole job. She deletes. She frees. She moves on.

---

🌸 C SPECIFICATION 🌸

void glDeleteLists( GLuint list,
                    GLsizei range )

that's it. two args. she's lowkey minimal about it 😌

---

🦋 PARAMETERS 🦋

• list — the integer name of the first display list you wanna delete. like, the first one. the starting point. the main character of the range 👑
• range — how many display lists to delete. the headcount. the vibes span 💀

---

🌈 DESCRIPTION 🌈

so here's the tea ☕ glDeleteLists causes a contiguous group of display lists to be deleted. list is the name of the first display list to be deleted, and range is the number of display lists to delete. and every single display list d where

list ≤ d ≤ list + range - 1

gets deleted. all of them. the whole squad. gone 🫶

all storage locations allocated to the specified display lists are freed, and the names are available for reuse at a later time — so it's not a forever goodbye, it's more like a "you can come back later" energy ♻️✨

and here's the part where she's chill: names within the range that do not have an associated display list are just ignored. she's not gonna yell at you about it. she's not gonna error out. she just moves on 😌

and if range is 0? nothing happens. literally nothing. zero. nada. a whole lot of nothing 💀

---

🔥 ERRORS 🔥

• GL_INVALID_VALUE is generated if range is negative. so like... don't do that 🙈 negative range is not the vibe, she will call you out.
• GL_INVALID_OPERATION is generated if glDeleteLists is executed between the execution of glBegin and the corresponding execution of glEnd. read that again, bestie — do not delete lists in the middle of a glBegin/glEnd sandwich. that's forbidden. she said no 🚫👑

fr fr, those two errors are not a drill. range < 0 = invalid value, and deleting between glBegin and glEnd = invalid operation. periodt.
