DRAWFCALL(3)

Welcome to DRAWFCALL(3), bestie — the Library Functions Manual page for the window system protocol, and yes she’s serving Unix group-chat energy 🫶✨

💖 NAME 💖

convM2W, convW2M, drawfcallfmt, readwsysmsg, sizeW2M — window system protocol 🪟💅

✨ SYNOPSIS ✨

Okay so first you gather the headers like you’re collecting stickers, no cap:

#include <u.h>
#include <libc.h>
#include <draw.h>
#include <mouse.h>
#include <cursor.h>
#include <drawfcall.h>

uint convM2W(uchar *ap, uint nap, Wsysmsg *w)

uint convW2M(Wsysmsg *w, uchar *ap, uint nap)

int  drawfcallfmt(Fmt*)

int  readwsysmsg(int fd, uchar *buf, uint nbuf)

uint sizeW2M(Wsysmsg *w)

🌸 DESCRIPTION 🌸

Okay so these routines are the analogues of the routines described in fcall(3), but make it graphics 💅 They manipulate graphics device protocol messages rather than 9P protocol messages. The graphics device protocol is used for internal communication between the devdraw(1) graphics server and the draw(3) library. A Wsysmsg is the C structure corresponding to a protocol message ✨

🚨 Heads up, bestie: the protocol is intentionally undocumented and may change. So don’t get too attached to any secret interpretation, fr fr 💀
