Author: Chia-I Wu <[email protected]> Date: Thu Feb 4 12:52:15 2010 +0800 egl: Add macros to define typecast functions. There are standard typecast functions that are common to most drivers. They are used to typecast, for example, an _EGLSurface to a driver-defined type. This commits define _EGL_DRIVER_STANDARD_TYPECASTS and _EGL_DRIVER_TYPECAST that should hopefully save some typings for driver writers. --- src/egl/main/egldriver.h | 21 +++++++++++++++++++++ 1 files changed, 21 insertions(+), 0 deletions(-) diff --git a/src/egl/main/egldriver.h b/src/egl/main/egldriver.h index 5149acd..c1e6fa2 100644 --- a/src/egl/main/egldriver.h +++ b/src/egl/main/egldriver.h @@ -6,6 +6,27 @@ #include "eglapi.h" +/** + * Define an inline driver typecast function. + */ +#define _EGL_DRIVER_TYPECAST(drvtype, egltype, code) \ + static INLINE struct drvtype *drvtype(const egltype *obj) \ + { return (struct drvtype *) code; } + + +/** + * Define the driver typecast functions for _EGLDriver, _EGLDisplay, + * _EGLContext, _EGLSurface, and _EGLConfig. + */ +#define _EGL_DRIVER_STANDARD_TYPECASTS(drvname) \ + _EGL_DRIVER_TYPECAST(drvname ## _driver, _EGLDriver, obj) \ + /* note that this is not a direct cast */ \ + _EGL_DRIVER_TYPECAST(drvname ## _display, _EGLDisplay, obj->DriverData) \ + _EGL_DRIVER_TYPECAST(drvname ## _context, _EGLContext, obj) \ + _EGL_DRIVER_TYPECAST(drvname ## _surface, _EGLSurface, obj) \ + _EGL_DRIVER_TYPECAST(drvname ## _config, _EGLConfig, obj) + + typedef _EGLDriver *(*_EGLMain_t)(const char *args); _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
