GLISENABLED() GLISENABLED() NAME glIsEnabled - test whether a capability is enabled C SPECIFICATION GLboolean glIsEnabled( GLenum cap ) PARAMETERS cap Specifies a symbolic constant indicating a GL capability. DESCRIPTION glIsEnabled returns GL_TRUE if cap is an enabled capability and returns GL_FALSE otherwise. Initially all capabilities except GL_DITHER are dis- abled; GL_DITHER is initially enabled. The following capabilities are accepted for cap: Constant See ----------------------------------------------------------------- GL_ALPHA_TEST glAlphaFunc GL_AUTO_NORMAL glEvalCoord GL_BLEND glBlendFunc, glLogicOp GL_CLIP_PLANEi glClipPlane GL_COLOR_ARRAY glColorPointer GL_COLOR_LOGIC_OP glLogicOp GL_COLOR_MATERIAL glColorMaterial GL_CULL_FACE glCullFace GL_DEPTH_TEST glDepthFunc, glDepthRange GL_DITHER glEnable GL_EDGE_FLAG_ARRAY glEdgeFlagPointer GL_FOG glFog GL_INDEX_ARRAY glIndexPointer GL_INDEX_LOGIC_OP glLogicOp GL_LIGHTi glLightModel, glLight GL_LIGHTING glMaterial, glLightModel, glLight GL_LINE_SMOOTH glLineWidth GL_LINE_STIPPLE glLineStipple GL_MAP1_COLOR_4 glMap1, glMap2 GL_MAP2_TEXTURE_COORD_2 glMap2 GL_MAP2_TEXTURE_COORD_3 glMap2 GL_MAP2_TEXTURE_COORD_4 glMap2 GL_MAP2_VERTEX_3 glMap2 GL_MAP2_VERTEX_4 glMap2 GL_NORMAL_ARRAY glNormalPointer GL_NORMALIZE glNormal GL_POINT_SMOOTH glPointSize GL_POLYGON_SMOOTH glPolygonMode GL_POLYGON_OFFSET_FILL glPolygonOffset GL_POLYGON_OFFSET_LINE glPolygonOffset GL_POLYGON_OFFSET_POINT glPolygonOffset GL_POLYGON_STIPPLE glPolygonStipple GL_SCISSOR_TEST glScissor GL_STENCIL_TEST glStencilFunc, glStencilOp GL_TEXTURE_1D glTexImage1D GL_TEXTURE_2D glTexImage2D GL_TEXTURE_COORD_ARRAY glTexCoordPointer GL_TEXTURE_GEN_Q glTexGen GL_TEXTURE_GEN_R glTexGen GL_TEXTURE_GEN_S glTexGen GL_TEXTURE_GEN_T glTexGen GL_VERTEX_ARRAY glVertexPointer NOTES If an error is generated, glIsEnabled returns 0.

GL_INVALID_OPERATION is generated if glIsEnabled is executed between the execution of glBegin and the corresponding execution of glEnd. SEE ALSO glEnable, glEnableClientState GLISENABLED()
