Call vga_init() to initialize the SVGA library. * 3. Call vga_setmode() to specify the screen size and color depth. * 4. Call SVGAMesaCreateContext() to setup a Mesa context. If using 8-bit * color Mesa assumes color index mode, if using 16-bit or deeper color * Mesa assumes RGB mode. * 5. Call SVGAMesaMakeCurrent() to activate the Mesa context. * 6. You can now use the Mesa API functions. * 7. Before exiting, call SVGAMesaDestroyContext() then vga_setmode(TEXT) * to restore the original text screen. * * Notes * 1. You must run your executable as root (or use the set UID-bit) because * the SVGA library requires it. * 2. The SVGA driver is not fully implemented yet. See svgamesa.c for what * has to be done yet. */ #ifndef SVGAMESA_H #define SVGAMESA_H #define SVGAMESA_MAJOR_VERSION 4 #define SVGAMESA_MINOR_VERSION 0 #ifdef __cplusplus extern "C" { #endif #include "GL/gl.h" /* * This is the SVGAMesa context 'handle': */ typedef struct svgamesa_context *SVGAMesaContext; /* * doubleBuffer flag new in version 2.4 */ extern int SVGAMesaInit( int GraphMode ); extern int SVGAMesaClose( void ); extern SVGAMesaContext SVGAMesaCreateContext( GLboolean doubleBuffer ); extern void SVGAMesaDestroyContext( SVGAMesaContext ctx ); extern void SVGAMesaMakeCurrent( SVGAMesaContext ctx ); extern void SVGAMesaSwapBuffers( void ); extern void SVGAMesaSetCI(int ndx, GLubyte red, GLubyte green, GLubyte blue); extern SVGAMesaContext SVGAMesaGetCurrentContext( void ); #ifdef __cplusplus } #endif #endif
