[henry]

Dear List:   For some reason,I need to write a test for videodev.c(a vga driver)           It's supposed that I could know how from source of Xlib But I cant get any msg by typing                 "grep -rw videodev.h /usr/X11R6 "           Could someone give hint ? or Someone know the spec of videodev.c ?     BestRegards Henry
