DESCRIPTION

28       glEnableClientState and glDisableClientState enable or disable individ‐
29       ual client-side capabilities. By default, all client-side  capabilities
30       are disabled.  Both glEnableClientState and glDisableClientState take a
31       single argument, 1.1, which can assume one of the following values:
32
33       GL_COLOR_ARRAY           If enabled, the color  array  is  enabled  for
34                                writing   and   used   during  rendering  when
35                                glArrayElement,  glDrawArrays,  glDrawElement,
36                                or    glDrawRangeElements   is   called.   See
37                                glColorPointer.
38
39       GL_EDGE_FLAG_ARRAY       If enabled, the edge flag array is enabled for
40                                writing   and   used   during  rendering  when
41                                glArrayElement,  glDrawArrays,  glDrawElement,
42                                or    glDrawRangeElements   is   called.   See
43                                glEdgeFlagPointer.
44
45       GL_INDEX_ARRAY           If enabled, the index  array  is  enabled  for
46                                writing   and   used   during  rendering  when
47                                glArrayElement,  glDrawArrays,  glDrawElement,
48                                or    glDrawRangeElements   is   called.   See
49                                glIndexPointer.
50
51       GL_NORMAL_ARRAY          If enabled, the normal array  is  enabled  for
52                                writing   and   used   during  rendering  when
53                                glArrayElement,  glDrawArrays,  glDrawElement,
54                                or    glDrawRangeElements   is   called.   See
55                                glNormalPointer.
56
57       GL_TEXTURE_COORD_ARRAY   If enabled, the texture  coordinate  array  is
58                                enabled  for writing and used during rendering
59                                when       glArrayElement,       glDrawArrays,
60                                glDrawElement,   or   glDrawRangeElements   is
61                                called. See glTexCoordPointer.
62
63       GL_VERTEX_ARRAY          If enabled, the vertex array  is  enabled  for
64                                writing   and   used   during  rendering  when
65                                glArrayElement,  glDrawArrays,  glDrawElement,
66                                or    glDrawRangeElements   is   called.   See
67                                glVertexPointer.

NOTES

70       glEnableClientState is available only if  the  GL  version  is  1.1  or
71       greater.
72
73       If   GL_ARB_multitexture   is   supported,   enabling   and   disabling
74       GL_TEXTURE_COORD_ARRAY affects the active  client  texture  unit.   The
75       active client texture unit is controlled with glClientActiveTextureARB.
76

ERRORS

78       GL_INVALID_ENUM is generated if 1.1 is not an accepted value.
79
80       glEnableClientState is not allowed between the execution of glBegin and
81       the corresponding glEnd, but an error may or may not be  generated.  If
82       no error is generated, the behavior is undefined.
