.SH DESCRIPTION
|
||
|
|
These routines are analogues of the routines described in
|
||
|
|
.IR fcall (3).
|
||
|
|
They manipulate graphics device protocol messages
|
||
|
|
rather than 9P protocol messages.
|
||
|
|
The graphics device protocol is used for internal
|
||
|
|
communication between the
|
||
|
|
.IR devdraw (1)
|
||
|
|
graphics server
|
||
|
|
and the
|
||
|
|
.IR draw (3)
|
||
|
|
library.
|
||
|
|
A
|
||
|
|
.B Wsysmsg
|
||
|
|
is the C structure corresponding to a protocol message.
|
||
|
|
.PP
|
||
|
|
The protocol is intentionally undocumented and may change.
