GLPOPDEBUGGROUP(3G)

✨ NAME ✨

glPopDebugGroup — bestie, this is the one that pops the active debug group 💅

(also hi, you're in section 3G of the manual, welcome 🫶)

---

🌸 C SPECIFICATION 🌸

void glPopDebugGroup(void);

that's it. that's the whole signature. no args, no drama, no cap ✨

---

🦋 DESCRIPTION 🦋

okay so glPopDebugGroup pops the active debug group. like, it takes the top one off the stack, done, slay 👑

but here's the tea: after popping a debug group, the GL will also generate a debug output message describing its cause — based on the message string, the source source, and an ID id that you submitted to the corresponding glPushDebugGroup() command. so it's not just silently removing stuff, it's literally filing a little report about it. main character energy fr fr 📝

some specifics so you don't get caught lacking:

• GL_DEBUG_TYPE_PUSH_GROUP and GL_DEBUG_TYPE_POP_GROUP share a single namespace for message id 👯
• severity has the value GL_DEBUG_SEVERITY_NOTIFICATION
• the type has the value GL_DEBUG_TYPE_POP_GROUP
• popping a debug group restores the debug output volume control of the parent debug group 🔊 (yes, the vibe check goes back up to the parent's level, iconic)

---

💀 ERRORS 💀

• GL_STACK_UNDERFLOW is generated if an attempt is made to pop the default debug group from the stack.

⚠️ like, do NOT try to pop the default debug group. there's nothing under it. the stack is empty. it will yell at you. consider this your warning bestie 😭

---

🎀 ASSOCIATED GETS 🎀

• glGet() with argument GL_MAX_DEBUG_MESSAGE_LENGTH.
