convM2W, convW2M, drawfcallfmt, readwsysmsg, sizeW2M – window system
protocol

SYNOPSIS
| |
#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
| |
These routines are analogues of the routines described in fcall(3).
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.
The protocol is intentionally undocumented and may change.
