GLISFRAMEBUFFER(3G)

okay so bestie, welcome to GLISFRAMEBUFFER(3G) — manual section 3G — and yes the header literally has [FIXME: manual] in it, we love a transparent icon 💅. This is the page for checking whether a name is giving framebuffer object, and we're gonna keep every single detail, no cap.

🌸 NAME 🌸

glIsFramebuffer — determine if a name corresponds to a framebuffer object.

💖 C SPECIFICATION 💖

GLboolean glIsFramebuffer(GLuint framebuffer);

🎀 PARAMETERS 🎀

• framebuffer — specifies a value that may be the name of a framebuffer object.

✨ DESCRIPTION ✨

So glIsFramebuffer returns GL_TRUE if framebuffer is currently the name of a framebuffer object. Simple, iconic, to the point.

If framebuffer is zero, or if framebuffer is not the name of a framebuffer object, or if an error occurs, glIsFramebuffer returns GL_FALSE.

And here's the little plot twist: if framebuffer is a name returned by glGenFramebuffers(), but it has not yet been bound through a call to glBindFramebuffer(), then that name is not a framebuffer object, and glIsFramebuffer returns GL_FALSE. Like, the name exists but the object vibe is not activated yet, iykyk.

🦋 VERSION SUPPORT 🦋

The table's header is Function / Feature Name on one side and OpenGL Version on the other, and the function row is glIsFramebuffer. Here's the support lookup, exactly as listed:

• 2.0 — -
• 2.1 — -
