"i got this functon from lcd 4 bit c code in google search." That is absolutely no help to anyone whatsoever! You have the code in front of you, and you know where it came from - so look at the code, and look at the supporting information for it. If it doesn't have supporting information, keep on goggling til you find something that is properly explained! Nobody else has any idea what code you're talking about, so can't possibly comment on it!
Probably you should write your LCD driver on your own. Using code from the internet makes only sense if you are able to understand it (without asking someone else). You should also read the datasheet for you display.
