-\fB#include "SDL\&.h"

-\fBvoid \fBSDL_UpdateRects\fP\fR(\fBSDL_Surface *screen, int numrects, SDL_Rect *rects\fR);
-.SH "DESCRIPTION"
-.PP
-Makes sure the given list of rectangles is updated on the given screen\&. The rectangles must all be confined within the screen boundaries (no clipping is done)\&.
-.PP
-This function should not be called while \fBscreen\fR is \fIlocked\fR\&.
-.PP
-.RS
-\fBNote:
-.PP
-It is adviced to call this function only once per frame, since each call has some processing overhead\&. This is no restriction since you can pass any number of rectangles each time\&.
-.PP
-The rectangles are not automatically merged or checked for overlap\&. In general, the programmer can use his knowledge about his particular rectangles to merge them in an efficient way, to avoid overdraw\&.
