GLENABLECLIENTSTATE(3G) 		  OpenGL Manual 		  GLENABLECLIENTSTATE(3G)

NAME
       glEnableClientState - enable or disable client-side capability

C SPECIFICATION
       void glEnableClientState(GLenum cap);

PARAMETERS
       cap
	   Specifies the capability to enable. Symbolic constants GL_COLOR_ARRAY,
	   GL_EDGE_FLAG_ARRAY, GL_FOG_COORD_ARRAY, GL_INDEX_ARRAY, GL_NORMAL_ARRAY,
	   GL_SECONDARY_COLOR_ARRAY, GL_TEXTURE_COORD_ARRAY, and GL_VERTEX_ARRAY are accepted.

C SPECIFICATION
       void glDisableClientState(GLenum cap);

PARAMETERS
       cap
	   Specifies the capability to disable.

DESCRIPTION
       glEnableClientState and glDisableClientState() enable or disable individual client-side
       capabilities. By default, all client-side capabilities are disabled. Both
       glEnableClientState and glDisableClientState() take a single argument, cap, which can
       assume one of the following values:

       GL_COLOR_ARRAY
	   If enabled, the color array is enabled for writing and used during rendering when
	   glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glColorPointer().

       GL_EDGE_FLAG_ARRAY
	   If enabled, the edge flag array is enabled for writing and used during rendering when
	   glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glEdgeFlagPointer().

       GL_FOG_COORD_ARRAY
	   If enabled, the fog coordinate array is enabled for writing and used during rendering
	   when glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glFogCoordPointer().

       GL_INDEX_ARRAY
	   If enabled, the index array is enabled for writing and used during rendering when
	   glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glIndexPointer().

       GL_NORMAL_ARRAY
	   If enabled, the normal array is enabled for writing and used during rendering when
	   glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glNormalPointer().

       GL_SECONDARY_COLOR_ARRAY
	   If enabled, the secondary color array is enabled for writing and used during rendering
	   when glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glColorPointer().

       GL_TEXTURE_COORD_ARRAY
	   If enabled, the texture coordinate array is enabled for writing and used during
	   rendering when glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glTexCoordPointer().

       GL_VERTEX_ARRAY
	   If enabled, the vertex array is enabled for writing and used during rendering when
	   glArrayElement(), glDrawArrays(), glDrawElements(),
	   glDrawRangeElements()glMultiDrawArrays(), or glMultiDrawElements() is called. See
	   glVertexPointer().

NOTES
       glEnableClientState is available only if the GL version is 1.1 or greater.

       GL_FOG_COORD_ARRAY and GL_SECONDARY_COLOR_ARRAY are available only if the GL version is
       1.4 or greater.

       For OpenGL versions 1.3 and greater, or when ARB_multitexture is supported, enabling and
       disabling GL_TEXTURE_COORD_ARRAY affects the active client texture unit. The active client
       texture unit is controlled with glClientActiveTexture().

ERRORS
       GL_INVALID_ENUM is generated if cap is not an accepted value.

       glEnableClientState is not allowed between the execution of glBegin() and the
       corresponding glEnd(), but an error may or may not be generated. If no error is generated,
       the behavior is undefined.
