glEnableClientState, glDisableClientState

The glEnableClientState and glDisableClientState functions enable and disable arrays respectively.

void glEnableClientState(
  GLenum array  );void glDisableClientState(  GLenum array  );

Parameters

• array
  A symbolic constant for the array you want to enable or disable. This parameter can assume one of the following values:

  Value	Meaning
  GL_COLOR_ARRAY	If enabled, use color arrays with calls to glArrayElement, glDrawElements, or glDrawArrays. See also glColorPointer.
  GL_EDGE_FLAG_ARRAY	If enabled, use edge flag arrays with calls to glArrayElement, glDrawElements, or glDrawArrays. See also glEdgeFlagPointer.
  GL_INDEX_ARRAY	If enabled, use index arrays with calls to glArrayElement, glDrawElements, or glDrawArrays. See also glIndexPointer.
  GL_NORMAL_ARRAY	If enabled, use normal arrays with calls to glArrayElement, glDrawElements, or glDrawArrays. See also glNormalPointer.
  GL_TEXTURE_COORD_ARRAY	If enabled, use texture coordinate arrays with calls to glArrayElement, glDrawElements, or glDrawArrays. See also glTexCoordPointer.
  GL_VERTEX_ARRAY	If enabled, use vertex arrays with calls to glArrayElement, glDrawElements, or glDrawArrays. See also glVertexPointer.

Remarks

The glEnableClientState and glDisableClientState functions enable and disable various individual arrays. Use glIsEnabled or glGet to determine the current setting of any capability.

Calling glEnableClientState and glDisableClientState between calls to glBegin and the corresponding call to glEnd can cause an error. If no error is generated, the behavior is undefined.

Note  The glEnableClientState and glDisableClientState functions are only available in OpenGL version 1.1 or later.
