Hi experts,

Basically I need to take a screenshot from the QNX board. When I refer the program given on qnx site at : 

http://www.qnx.com/developers/docs/660/index.jsp?topic=/com.qnx.doc.screen/topic/manual/cscreen_screenshot_disp_sample.
html 

I am able to get the screenshot, but in this program  screen_create_context uses SCREEN_DISPLAY_MANAGER_CONTEXT., which 
obviously needs  a root permission.

Whereas in my actual program I won't be a root user,but still i need to take a screenshot. For this i referred program 
at: http://www.qnx.com/developers/docs/660/index.jsp?topic=%2Fcom.qnx.doc.screen%2Ftopic%2Fmanual%
2Fcscreen_screenshot_win_sample.html 

Here it uses context as screen_create_context(&screen_ctx, SCREEN_APPLICATION_CONTEXT); but the screenshot is blank, 
with just a black image that I am not supposed to get.

Please let me know if there is an alternate way to do it !!!!!

Thanks in advance,
Rupali
