The screen_create_context() function tries to establish communication with the composited windowing system resource manager (Screen). To do this, the function opens /dev/screen and sends the proper connect sequence. If the call succeeds, memory is allocated to store context state. The composition manager then creates an event queue and associates it with the connecting process.
0 if the context was created, or -1 if an error occurred (errno is set; refer to /usr/include/errno.h for more details).
