🦋 REPLY FIELDS 🦋

• response_type — the type of this reply, and in this case it's XCB_XV_QUERY_PORT_ATTRIBUTES. This field also lives inside xcb_generic_reply_t, so you can use it to tell your replies apart from each other 👑
• sequence — the sequence number of the last request the X11 server actually processed 🔢
• length — how long the reply is, in words (and a word is 4 bytes, that's the unit, periodt) 📏
• num_attributes — TODO: NOT YET DOCUMENTED. 💀
• text_size — TODO: NOT YET DOCUMENTED. 💀

And that's the whole page, bestie!! 🎀 This one came from X Version 11, shipped with libxcb 1.17.0, and it's the manual for xcb_xv_query_port_attributes(3). Go query those port attributes, you absolute main character 👑💅✨
