dlls/opengl32/tests/opengl.c --snip-- const int iAttribList[] = { WGL_COLOR_BITS_ARB, WGL_RED_BITS_ARB, WGL_GREEN_BITS_ARB, WGL_BLUE_BITS_ARB, WGL_ALPHA_BITS_ARB }; int iAttribRet[sizeof(iAttribList)/sizeof(iAttribList[0])]; const int iAttribs[] = { WGL_ALPHA_BITS_ARB, 1, 0 }; unsigned int nFormats; int res; int iPixelFormat = 0; --snip-- iAttribRet[1] += iAttribRet[2]+iAttribRet[3]+iAttribRet[4]; ok(iAttribRet[0] == iAttribRet[1], "WGL_COLOR_BITS_ARB (%d) does not equal R+G+B+A (%d)!\n", iAttribRet[0], iAttribRet[1]); } --snip--
