GLINDEXPOINTER(3gl)					   GLINDEXPOINTER(3gl)

NAME
       glIndexPointer - define an array of color indexes

C SPECIFICATION
       void glIndexPointer( GLenum type,
			    GLsizei stride,
			    const GLvoid *pointer )

PARAMETERS
       type	Specifies  the	data  type  of	each color index in the array.
		Symbolic   constants   GL_UNSIGNED_BYTE,   GL_SHORT,   GL_INT,
		GL_FLOAT, and GL_DOUBLE are accepted.

       stride	Specifies  the	byte offset between consecutive color indexes.
		If stride is 0 (the initial  value),  the  color  indexes  are
		understood to be tightly packed in the array.

       pointer	Specifies a pointer to the first index in the array.

DESCRIPTION
       glIndexPointer  specifies  the  location and data format of an array of
       color indexes to use when rendering.  type specifies the data  type  of
       each  color index and stride gives the byte stride from one color index
       to the next allowing vertexes and attributes to be packed into a single
       array  or stored in separate arrays.  (Single-array storage may be more
       efficient on some implementations; see glInterleavedArrays.)

       type, stride, and pointer are saved as client-side state.

       The color index array is initially disabled. To enable and disable  the
       array, call glEnableClientState and glDisableClientState with the argu‐
       ment GL_INDEX_ARRAY. If enabled, the color index	 array	is  used  when
       glDrawArrays, glDrawElements or glArrayElement is called.

       Use glDrawArrays to construct a sequence of primitives (all of the same
       type) from prespecified vertex and vertex attribute arrays.  Use	 glAr‐
       rayElement  to  specify	primitives  by	indexing  vertexes  and vertex
       attributes and glDrawElements to construct a sequence of primitives  by
       indexing vertexes and vertex attributes.

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

       The color index array is initially disabled, and it isn't accessed when
       glArrayElement, glDrawElements or glDrawArrays is called.

       Execution of glIndexPointer is not allowed between glBegin and the cor‐
       responding glEnd, but an error may or may not be generated. If an error
       is not generated, the operation is undefined.

       glIndexPointer is typically implemented on the client side.

       Since the color index array parameters are client-side state, they  are
       not  saved  or  restored	 by glPushAttrib and glPopAttrib.  Use glPush‐
       ClientAttrib and glPopClientAttrib instead.

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

       GL_INVALID_VALUE is generated if stride is negative.

ASSOCIATED GETS
       glIsEnabled with argument GL_INDEX_ARRAY
       glGet with argument GL_INDEX_ARRAY_TYPE
       glGet with argument GL_INDEX_ARRAY_STRIDE
       glGetPointerv with argument GL_INDEX_ARRAY_POINTER
