GLSECONDARYCOLORPOIN(3G)	 OpenGL Manual	      GLSECONDARYCOLORPOIN(3G)

NAME
       glSecondaryColorPointer - define an array of secondary colors

C SPECIFICATION
       void glSecondaryColorPointer(GLint size, GLenum type, GLsizei stride,
				    const GLvoid * pointer);

PARAMETERS
       size
	   Specifies the number of components per color. Must be 3.

       type
	   Specifies the data type of each color component in the array.
	   Symbolic constants GL_BYTE, GL_UNSIGNED_BYTE, GL_SHORT,
	   GL_UNSIGNED_SHORT, GL_INT, GL_UNSIGNED_INT, GL_FLOAT, or GL_DOUBLE
	   are accepted. The initial value is GL_FLOAT.

       stride
	   Specifies the byte offset between consecutive colors. If stride is
	   0, the colors are understood to be tightly packed in the array. The
	   initial value is 0.

       pointer
	   Specifies a pointer to the first component of the first color
	   element in the array. The initial value is 0.

DESCRIPTION
       glSecondaryColorPointer specifies the location and data format of an
       array of color components to use when rendering.	 size specifies the
       number of components per color, and must be 3.  type specifies the data
       type of each color component, and stride specifies the byte stride from
       one color to the next, allowing vertices and attributes to be packed
       into a single array or stored in separate arrays.

       If a non-zero named buffer object is bound to the GL_ARRAY_BUFFER
       target (see glBindBuffer()) while a secondary color array is specified,
       pointer is treated as a byte offset into the buffer object's data
       store. Also, the buffer object binding (GL_ARRAY_BUFFER_BINDING) is
       saved as secondary color vertex array client-side state
       (GL_SECONDARY_COLOR_ARRAY_BUFFER_BINDING).

       When a secondary color array is specified, size, type, stride, and
       pointer are saved as client-side state, in addition to the current
       vertex array buffer object binding.

       To enable and disable the secondary color array, call
       glEnableClientState() and glDisableClientState() with the argument
       GL_SECONDARY_COLOR_ARRAY. If enabled, the secondary color array is used
       when glArrayElement(), glDrawArrays(), glMultiDrawArrays(),
       glDrawElements(), glMultiDrawElements(), or glDrawRangeElements() is
       called.

NOTES
       glSecondaryColorPointer is available only if the GL version is 1.4 or
       greater.

       Secondary colors are not supported for interleaved vertex array formats
       (see glInterleavedArrays()).

       The secondary color array is initially disabled and isn't accessed when
       glArrayElement(), glDrawElements(), glDrawRangeElements(),
       glDrawArrays(), glMultiDrawArrays(), or glMultiDrawElements() is
       called.

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

       glSecondaryColorPointer is typically implemented on the client side.

       Secondary color array parameters are client-side state and are
       therefore not saved or restored by glPushAttrib() and glPopAttrib().
       Use glPushClientAttrib() and glPopClientAttrib() instead.

ERRORS
       GL_INVALID_VALUE is generated if size is not 3.

       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_SECONDARY_COLOR_ARRAY

       glGet() with argument GL_SECONDARY_COLOR_ARRAY_SIZE

       glGet() with argument GL_SECONDARY_COLOR_ARRAY_TYPE

       glGet() with argument GL_SECONDARY_COLOR_ARRAY_STRIDE

       glGet() with argument GL_SECONDARY_COLOR_ARRAY_BUFFER_BINDING

       glGet() with argument GL_ARRAY_BUFFER_BINDING

       glGetPointerv() with argument GL_SECONDARY_COLOR_ARRAY_POINTER
