GLENABLECLIENTSTATE(3G) 												   GLENABLECLIENTSTATE(3G)

NAME

       glEnableClientState, glDisableClientState - enable or disable client-side capability

C SPECIFICATION

       void glEnableClientState( GLenum array )

PARAMETERS

       array  Specifies  the  capability  to  enable.	Symbolic  constants  GL_COLOR_ARRAY,  GL_EDGE_FLAG_ARRAY, GL_INDEX_ARRAY, GL_NORMAL_ARRAY,
	      GL_TEXTURE_COORD_ARRAY, and GL_VERTEX_ARRAY are accepted.

C SPECIFICATION

       void glDisableClientState( GLenum array )

PARAMETERS

       array  Specifies the capability to disable.

DESCRIPTION

       glEnableClientState and glDisableClientState enable or disable individual client-side capabilities. By default, all  client-side  capabili-
       ties  are disabled.  Both glEnableClientState and glDisableClientState take a single argument, array, 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,
				glDrawElement, or glDrawRangeElements 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, glDrawElement, or glDrawRangeElements is called. See glEdgeFlagPointer.

       GL_INDEX_ARRAY		If enabled, the index array is enabled for writing and used during rendering  when  glArrayElement,  glDrawArrays,
				glDrawElement, or glDrawRangeElements is called. See glIndexPointer.

       GL_NORMAL_ARRAY		If  enabled,  the normal array is enabled for writing and used during rendering when glArrayElement, glDrawArrays,
				glDrawElement, or glDrawRangeElements is called. See glNormalPointer.

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

       GL_VERTEX_ARRAY		If  enabled,  the vertex array is enabled for writing and used during rendering when glArrayElement, glDrawArrays,
				glDrawElement, or glDrawRangeElements is called. See glVertexPointer.

NOTES

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

       If GL_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 glClientActiveTextureARB.

ERRORS

       GL_INVALID_ENUM is generated if array 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.

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.
