I'm interested in porting an app in Fortran from the PC to a sun 3workstation.
All of the graphics are very straight-forward, being only line draws, etc,
but there seems to be a major point of contention. In X, to do the same sort
of "non-event driven" sort of  thing, I just placed an XPending after every 
output, so that the buffer is flushed, whether an event is pending or not.
I can't seem to find an equivalent call in SunView. The only way I can generate
any output is via the window_main_loop(frame) call, which then proceeds to block
until something is done. In order that I might not have to completely rewrite
the Fortran code to accomodate the event-driven nature, (BTW, I will need access
to the mouse as well), does SunView provide such a beast that functions like
XPending? If not, any suggestions?
