✨ NAME ✨

okay so this page is GLINVALIDATEBUFFERDA(3G), and the function is glInvalidateBufferData. Its whole job is invalidating the content of a buffer object’s data store. No cap. 💅

🌸 C SPECIFICATION 🌸

void glInvalidateBufferData(GLuint buffer);

🎀 PARAMETERS 🎀

  • buffer — the name of a buffer object whose data store to invalidate. That’s the vibe, bestie.

💖 DESCRIPTION 💖

glInvalidateBufferData invalidates all of the content of the data store of a buffer object. After invalidation, the content of the buffer’s data store becomes undefined — like, do not trust it, do not expect your old data back, it’s giving “no thoughts, head empty” 😭.

🔥 ERRORS 🔥

  • GL_INVALID_VALUE is generated if buffer is not the name of an existing buffer object. Basically if you made up a buffer name, GL is like “who is she?” 💀
  • GL_INVALID_OPERATION is generated if any part of buffer is currently mapped. Mapped buffer + invalidation = nope, not today.

🦋 ASSOCIATED GETS 🦋

  • glGetBufferParameter() with argument GL_BUFFER_SIZE — that’s the getter bff you’d use here.
