+.SH "NAME"
+SDL_BlitSurface\- This performs a fast blit from the source surface to the destination surface\&.
+.SH "SYNOPSIS"
+.PP
+\fB#include "SDL\&.h"
+.sp
+\fBint \fBSDL_BlitSurface\fP\fR(\fBSDL_Surface *src, SDL_Rect *srcrect, SDL_Surface *dst, SDL_Rect *dstrect\fR);
+.SH "DESCRIPTION"
+.PP
+This performs a fast blit from the source surface to the destination surface\&.
+.PP
+Only the position is used in the \fBdstrect\fR (the width and height are ignored)\&.
+.PP
+If either \fBsrcrect\fR or \fBdstrect\fR are \fBNULL\fP, the entire surface (\fBsrc\fR or \fBdst\fR) is copied\&.
+.PP
+The final blit rectangle is saved in \fBdstrect\fR after all clipping is performed (\fBsrcrect\fR is not modified)\&.
+.PP
+The blit function should not be called on a locked surface\&.
+.PP
+.RS
+\fBNote:  
+.PP
+The results of blitting operations vary greatly depending on whether \fBSDL_SRCAPLHA\fP is set or not\&. See \fISDL_SetAlpha\fR\&.
+.RE
+.SH "RETURN VALUE"
+.PP
+If the blit is successful, it returns \fB0\fR, otherwise it returns \fB-1\fR\&.
+.PP
+If either of the surfaces were in video memory, and the blit returns \fB-2\fR, the video memory was lost, so it should be reloaded with artwork and re-blitted: 
+.PP
+.nf
+\f(CW        while ( SDL_BlitSurface(image, imgrect, screen, dstrect) == -2 ) {
+                while ( SDL_LockSurface(image)) < 0 )
+                        Sleep(10);
+                -- Write image pixels to image->pixels --
+                SDL_UnlockSurface(image);
+        }\fR
+.fi
+.PP
+ This happens under DirectX 5\&.0 when the system switches away from your fullscreen application\&. Locking the surface will also fail until you have access to the video memory again\&.
