-.TH "SDL_LockSurface" "3" "Tue 11 Sep 2001, 23:01" "SDL" "SDL API Reference" 
-.SH "NAME"
-SDL_LockSurface \- Lock a surface for directly access\&.
-.SH "SYNOPSIS"
-.PP
-\fB#include "SDL\&.h"
-.sp
-\fBint \fBSDL_LockSurface\fP\fR(\fBSDL_Surface *surface\fR);
-.SH "DESCRIPTION"
-.PP
-\fBSDL_LockSurface\fP sets up a surface for directly accessing the pixels\&. Between calls to \fBSDL_LockSurface\fP and \fBSDL_UnlockSurface\fP, you can write to and read from \fBsurface->\fBpixels\fR\fR, using the pixel format stored in \fBsurface->\fBformat\fR\fR\&. Once you are done accessing the surface, you should use \fBSDL_UnlockSurface\fP to release it\&.
-.PP
-Not all surfaces require locking\&. If \fBSDL_MUSTLOCK\fP(\fBsurface\fR) evaluates to \fB0\fR, then you can read and write to the surface at any time, and the pixel format of the surface will not change\&. 
-.PP
-No operating system or library calls should be made between lock/unlock pairs, as critical system locks may be held during this time\&.
-.PP
-It should be noted, that since SDL 1\&.1\&.8 surface locks are recursive\&. This means that you can lock a surface multiple times, but each lock must have a match unlock\&.
