GLOBJECTPTRLABEL(3G)

💖 NAME 💖

okay so bestie, this is glObjectPtrLabel — and what it does is label a sync object identified by a pointer. that's it, that's the whole gig ✨

this is a page from the 3G manual, and it's literally about giving your sync objects cute little name tags so debugging doesn't make you cry 🫶

---

🌸 C SPECIFICATION 🌸

here's the signature, copied exactly, don't @ me:

void glObjectPtrLabel(void * ptr, GLsizei length, const char * label);

---

🎀 PARAMETERS 🎀

• ptr — a pointer that identifies a sync object. yes, a whole pointer. main character energy tbh 👑
• length — the length of the label you're gonna use for the object. how many characters we talkin'
• label — the address of a string containing the label to assign to the object. like, the actual name tag 🏷️

---

🦋 DESCRIPTION 🦋

so glObjectPtrLabel labels the sync object identified by ptr. lowkey iconic, highkey useful 💅

label is the address of a string that's gonna be used to label the object. length contains the number of characters in label. and here's the tea:

• if length is negative, it's implied that label contains a null-terminated string 🧵
• if label is NULL, any debug label is effectively removed from the object 🗑️✨

---

⭐ ERRORS ⭐

these are the vibe checks that fail, no cap:

• GL_INVALID_VALUE is generated if ptr is not a valid sync object 💀
• GL_INVALID_VALUE is generated if the number of characters in label, excluding the null terminator when length is negative, is greater than the value of GL_MAX_LABEL_LENGTH 😭

fr fr bestie, keep your labels short or the spec will simply not let you live 🙈

---

🌈 ASSOCIATED GETS 🌈

• glGet() with argument GL_MAX_LABEL_LENGTH — go check how many characters you're allowed, iykyk

👑 VERSION SUPPORT 👑

okay so the original had a whole pretty grid and i can't do tables here, so here's the exact same info in list form, nothing skipped, periodt:

• glObjectPtrLabel — OpenGL 2.0: -
• glObjectPtrLabel — OpenGL 2.1: -
• glObjectPtrLabel — OpenGL 3.0: -
• glObjectPtrLabel — OpenGL 3.1: -
• glObjectPtrLabel — OpenGL 3.2: -
• glObjectPtrLabel — OpenGL 3.3: -
• glObjectPtrLabel — OpenGL 4.0: -
• glObjectPtrLabel — OpenGL 4.1: -
• glObjectPtrLabel — OpenGL 4.2: -
• glObjectPtrLabel — OpenGL 4.3: ✔
• glObjectPtrLabel — OpenGL 4.4: ✔

so uh yeah, it's giving "4.3 and up only" 💅 4.0, 4.1, 4.2? not invited to the party 🙈
