HI
thanks for suggestion. Since i want to scroll the text so i have to
update it regularly so i have taken a CAOPenGLLayer and set is
asynchronous and i am using
- (void)drawInCGLContext:(CGLContextObj)glContext pixelFormat:
(CGLPixelFormatObj)pixelFormat forLayerTime:
(CFTimeInterval)timeInterval displayTime:(const CVTimeStamp *)timeStamp
this fuction to update text.
Is this the right approach to do it.

Don't. Use a CATextLayer (which can render text for you) or a
CALayer (to display image content) instead. Unless you want to get
outlines of your text, the CAOpenGLLayer is really not a good way
to do this.
Clarifying a bit - unless you want to render your text as vector
graphics, then you don't want to use an OpenGL layer to do this.
