GLISLIST(3G)

💖 GLISLIST — the glIsList page, but make it make sense 💖

okay bestie, so this is a page from section 3G of the manual (that's the OpenGL library section, iykyk ✨). Sit down, grab a strawberry 🍓, and let's talk about how to find out if a name is actually a display-list name.

🎀 NAME 🎀

glIsList — the little detective that tells you whether a name corresponds to a display-list 🔍✨

💅 C SPECIFICATION 💅

GLboolean glIsList( GLuint list )

that's it. one function, one argument, returns a GLboolean. iconic behavior, no notes 👑

🦋 PARAMETERS 🦋

  • list — Specifies a potential display-list name. key word: potential. we don't know yet, that's literally the whole point of this function, that's the vibe check 🌸

✨ DESCRIPTION ✨

So here's the tea 🫖: glIsList returns GL_TRUE if list is the name of a display list, and returns GL_FALSE otherwise. That's the entire plot. no cap. 🎀

like, you hand it a name, it tells you yes or no. main character energy from a boolean. periodt 💅

💀 ERRORS 💀

🚨 GL_INVALID_OPERATION is generated if glIsList is executed between the execution of glBegin and the corresponding execution of glEnd. 🚨

translating: do not call this bad boy while you're inside a glBegin/glEnd block. not the time, not the place. you will get an error and honestly you'll deserve it 🙈💀

👑 SEE ALSO 👑

go read these next, bestie, they're the whole friend group fr fr:

  • glCallList(3G)
  • glCallLists(3G)
  • glDeleteLists(3G)
  • glGenLists(3G)
  • glNewList(3G)

okay and that's the whole page 🌈 thanks for coming to my TED talk. this was GLISLIST(3G), and yes the footer is literally just the title again — the manpage said its own name twice, which is such a Leo move 💅💖 slay, stay hydrated, and go check your display list names 🧚✨
