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.
