GLDELETEFRAMEBUFFERS(3G)

💅 GLDELETEFRAMEBUFFERS

okay bestie so this one is glDeleteFramebuffers from the OpenGL manual pages, section 3G — yes the 3G is the manual name, we're fancy like that ✨

---

🌸 NAME 🌸

glDeleteFramebuffers — delete framebuffer objects. it's giving cleanup era, it's giving "we're done with you, FBO" 💀

---

🎀 C SPECIFICATION 🎀

void glDeleteFramebuffers(GLsizei n, GLuint *framebuffers);

literally just two things, no cap:

---

✨ PARAMETERS ✨

• n — how many framebuffer objects you're yeeting today. the count, the number, the quantity 🗑️
• framebuffers — a pointer to an array holding those n framebuffer objects you want deleted. so like, a lil list of names, and this points at it 🫶

---

💖 DESCRIPTION 💖

glDeleteFramebuffers deletes the n framebuffer objects whose names are stored in the array addressed by framebuffers. just vibes, just deleting 💅

the name zero is reserved by the GL and is silently ignored should it occur in framebuffers — same energy as other unused names, also silently ignored. no drama, no error, just ignored 🙈

once a framebuffer object is deleted, its name is again unused and it has no attachments. like, the name goes back in the pool and the object is fully un-decorated. icon behavior ✨

and here's the spicy part 👑 — if a framebuffer that is currently bound to one or more of the targets GL_DRAW_FRAMEBUFFER or GL_READ_FRAMEBUFFER gets deleted, it is as though glBindFramebuffer() had been executed with the corresponding target and framebuffer zero. so the binding lowkey resets itself to zero. main character cleanup energy, fr fr 🌈

---

🦋 ERRORS 🦋

• GL_INVALID_VALUE is generated if n is negative. bestie. you cannot delete a negative number of framebuffers. that's not a thing 😭 negative counts are not slay, they're an error 💀

---

⭐ VERSION SUPPORT ⭐

the vibe check across OpenGL versions for glDeleteFramebuffers:

• OpenGL 2.0 — - (nope, not here 🙅)
• OpenGL 2.1 — - (still a no 🙅)
• OpenGL 3.0 — ✔
• OpenGL 3.1 — ✔
• OpenGL 3.2 — ✔
• OpenGL 3.3 — ✔
• OpenGL 4.0 — ✔
• OpenGL 4.1 — ✔
• OpenGL 4.2 — ✔
• OpenGL 4.3 — ✔
• OpenGL 4.4 — ✔
• OpenGL 4.5 — ✔

so basically: not in 2.0 or 2.1, and then present and accounted for all the way from 3.0 through 4.5. ate and left zero crumbs 🔥

🎀 okay that's the whole page, bestie — and one tiny housekeeping note: the source line on this one is literally [FIXME: source] and the date is 08/09/2021, so the version info is still a work in progress, ngl 😭 but everything else? slayed. bye babe 💜✨
