This header file serves as the documentation for - * the Mesa/X11 interface functions. - * - * Note: this interface isn't intended for user programs. It's primarily - * just for implementing the pseudo-GLX interface. - */ - - -/* Sample Usage: - -In addition to the usual X calls to select a visual, create a colormap -and create a window, you must do the following to use the X/Mesa interface: - -1. Call XMesaCreateVisual() to make an XMesaVisual from an XVisualInfo. - -2. Call XMesaCreateContext() to create an X/Mesa rendering context, given - the XMesaVisual. - -3. Call XMesaCreateWindowBuffer() to create an XMesaBuffer from an X window - and XMesaVisual. - -4. Call XMesaMakeCurrent() to bind the XMesaBuffer to an XMesaContext and - to make the context the current one. - -5. Make gl* calls to render your graphics. - -6. Use XMesaSwapBuffers() when double buffering to swap front/back buffers. - -7. Before the X window is destroyed, call XMesaDestroyBuffer(). - -8. Before exiting, call XMesaDestroyVisual and XMesaDestroyContext. - -*/ - - - - -#ifndef XMESA_H -#define XMESA_H - -#ifdef __VMS -#include <GL/vms_x_fix.h> -#endif - -#ifdef __cplusplus -extern "C" { -#endif - -#ifdef XFree86Server -#include "xmesa_xf86.h" -#else -#include <X11/Xlib.h> -#include <X11/Xutil.h> -#include "xmesa_x.h" -#endif -#include "GL/gl.h" - -#ifdef AMIWIN -#include <pragmas/xlib_pragmas.h> -extern struct Library *XLibBase; -#endif - - -#define XMESA_MAJOR_VERSION 6 -#define XMESA_MINOR_VERSION 3 - - - -/* - * Values passed to XMesaGetString: - */ -#define XMESA_VERSION 1 -#define XMESA_EXTENSIONS 2 - - -/* - * Values passed to XMesaSetFXmode: - */ -#define XMESA_FX_WINDOW 1 -#define XMESA_FX_FULLSCREEN 2 - - - -typedef struct xmesa_context *XMesaContext; - -typedef struct xmesa_visual *XMesaVisual; - -typedef struct xmesa_buffer *XMesaBuffer; - - - -/* - * Create a new X/Mesa visual. - * Input: display - X11 display - * visinfo - an XVisualInfo pointer - * rgb_flag - GL_TRUE = RGB mode, - * GL_FALSE = color index mode - * alpha_flag - alpha buffer requested? - * db_flag - GL_TRUE = double-buffered, - * GL_FALSE = single buffered - * stereo_flag - stereo visual? - * ximage_flag - GL_TRUE = use an XImage for back buffer, - * GL_FALSE = use an off-screen pixmap for back buffer - * depth_size - requested bits/depth values, or zero - * stencil_size - requested bits/stencil values, or zero - * accum_red_size - requested bits/red accum values, or zero - * accum_green_size - requested bits/green accum values, or zero - * accum_blue_size - requested bits/blue accum values, or zero - * accum_alpha_size - requested bits/alpha accum values, or zero - * num_samples - number of samples/pixel if multisampling, or zero - * level - visual level, usually 0 - * visualCaveat - ala the GLX extension, usually GLX_NONE_EXT - * Return; a new XMesaVisual or 0 if error. - */ -extern XMesaVisual XMesaCreateVisual( XMesaDisplay *display, - XMesaVisualInfo visinfo, - GLboolean rgb_flag, - GLboolean alpha_flag, - GLboolean db_flag, - GLboolean stereo_flag, - GLboolean ximage_flag, - GLint depth_size, - GLint stencil_size, - GLint accum_red_size, - GLint accum_green_size, - GLint accum_blue_size, - GLint accum_alpha_size, - GLint num_samples, - GLint level, - GLint visualCaveat ); - -/* - * Destroy an XMesaVisual, but not the associated XVisualInfo. - */ -extern void XMesaDestroyVisual( XMesaVisual v ); - - - -/* - * Create a new XMesaContext for rendering into an X11 window. - * - * Input: visual - an XMesaVisual - * share_list - another XMesaContext with which to share display - * lists or NULL if no sharing is wanted. - * Return: an XMesaContext or NULL if error. - */ -extern XMesaContext XMesaCreateContext( XMesaVisual v, - XMesaContext share_list ); - - -/* - * Destroy a rendering context as returned by XMesaCreateContext() - */ -extern void XMesaDestroyContext( XMesaContext c ); - - -#ifdef XFree86Server -/* - * These are the extra routines required for integration with XFree86. - * None of these routines should be user visible. -KEM - */ -extern GLboolean XMesaForceCurrent( XMesaContext c ); - -extern GLboolean XMesaLoseCurrent( XMesaContext c ); - -extern GLboolean XMesaCopyContext( XMesaContext src, - XMesaContext dst, - GLuint mask ); -#endif /* XFree86Server */ - - -/* - * Create an XMesaBuffer from an X window. - */ -extern XMesaBuffer XMesaCreateWindowBuffer( XMesaVisual v, XMesaWindow w ); - - -/* - * Create an XMesaBuffer from an X pixmap. - */ -extern XMesaBuffer XMesaCreatePixmapBuffer( XMesaVisual v, - XMesaPixmap p, - XMesaColormap cmap ); - - -/* - * Destroy an XMesaBuffer, but not the corresponding window or pixmap. - */ -extern void XMesaDestroyBuffer( XMesaBuffer b ); - - -/* - * Return the XMesaBuffer handle which corresponds to an X drawable, if any. - * - * New in Mesa 2.3. - */ -extern XMesaBuffer XMesaFindBuffer( XMesaDisplay *dpy, - XMesaDrawable d ); - - - -/* - * Bind a buffer to a context and make the context the current one. - */ -extern GLboolean XMesaMakeCurrent( XMesaContext c, - XMesaBuffer b ); - - -/* - * Bind two buffers (read and draw) to a context and make the - * context the current one. - * New in Mesa 3.3 - */ -extern GLboolean XMesaMakeCurrent2( XMesaContext c, - XMesaBuffer drawBuffer, - XMesaBuffer readBuffer ); - - -/* - * Unbind the current context from its buffer. - */ -extern GLboolean XMesaUnbindContext( XMesaContext c ); - - -/* - * Return a handle to the current context. - */ -extern XMesaContext XMesaGetCurrentContext( void ); - - -/* - * Return handle to the current (draw) buffer. - */ -extern XMesaBuffer XMesaGetCurrentBuffer( void ); - - -/* - * Return handle to the current read buffer. - * New in Mesa 3.3 - */ -extern XMesaBuffer XMesaGetCurrentReadBuffer( void ); - - -/* - * Swap the front and back buffers for the given buffer.
