The application I'm writing needs to determine the maximum number of lines that can be drawn with a single call to XDrawLines. In the O'Reilly manual it says this number is XMaxSizeRequest(display) - 3. HOWEVER, XMaxSizeRequest is neither mentioned in the protocol reference manual or the Xlib reference manual. Anyway, my program compiles without any problems (meaning we do have such an animal) but dies with a segment- ation violation as soon as it calls XMaxSizeRequest, which leads me to conclude that I'm not passing the right arguments -- if indeed this is the right function at all. Do any of you know what is going on here? What is the proper procedure under standard X11R4 for determining how many lines can be drawn using XDrawLines? What, then is this XMaxSizeRequest, and why isn't it documednted? I'm using Openwindow 2.0 under SunOS 4.1 . Thanks in advance! Gregory Woodhouse gjw@ags.wr.usgs.gov
