           31 .SH DESCRIPTION
           32 These routines are analogues of the routines described in 
           33 .MR fcall (3) .
           34 They manipulate graphics device protocol messages
           35 rather than 9P protocol messages.
           36 The graphics device protocol is used for internal 
           37 communication between the
           38 .MR devdraw (1)
           39 graphics server
           40 and the
           41 .MR draw (3)
           42 library.
           43 A
           44 .B Wsysmsg
           45 is the C structure corresponding to a protocol message.
           46 .PP
           47 The protocol is intentionally undocumented and may change.
