WAFFLE_GET_PROC_ADDR(3)

💖 WAFFLE_GET_PROC_ADDR 💖

okay so bestie, we're in the Waffle Manual section, and today's main character is waffle_get_proc_address(3) — the little function that goes "hey, where does this OpenGL function live?" and hands you back an address. let's get into it 🫶

---

✨ NAME ✨

waffle_get_proc_address — like, ask nicely for the address of OpenGL functions 💅

---

🌸 SYNOPSIS 🌸

#include <waffle.h>

void* waffle_get_proc_address(const char *name);

---

🦋 DESCRIPTION 🦋

so waffle_get_proc_address() is a little bit of a shape-shifter, no cap. here's the tea per platform:

• On GLX, this redirects to glXGetProcAddress(3). slay.
• On EGL, this redirects to eglGetProcAddress(3). also slay.
• On CGL, this function returns NULL because there exists no CGLGetProcAdress(). 😭 tragic, i know.
• On WGL, this redirects to wglGetProcAddress(3). back to slaying.

lowkey some aspects of this function's behavior are platform-specific and non-intuitive. for example:

• If the queried function is not available, waffle_get_proc_address() may return a non-null pointer. ikr. 🫠
• If the queried function is statically exposed by the OpenGL library of a given API, then waffle_get_proc_address() may return a NULL.
• Under Windows (WGL) a current context must be available before executing the function. otherwise waffle_get_proc_address() may return a NULL. no context, no address, that's the vibe check. 💀

if you want the full details on this function's behavior, go read the spec for the relevant platform, bestie: the GLX 1.4 Specification[1], the EGL 1.4 Specification[2], or the MSDN article[3]. iykyk 📚

but fr fr — no errors are specific to any functions listed in this manual page. clean. no drama. 🎀
