.SH PARAMETERS
_phead(_param1)
Specifies the number of components per color. Must be 3 or 4.
The initial value is 4.
_phead(_param2)
Specifies the data type of each color component in the array.
Symbolic constants
_const(BYTE),
_const(UNSIGNED_BYTE),
_const(SHORT),
_const(UNSIGNED_SHORT),
_const(INT),
_const(UNSIGNED_INT),
_const(FLOAT),
and
_const(DOUBLE)
are accepted.
The initial value is _const(FLOAT).
_phead(_param3)
Specifies the byte offset between consecutive colors.
If _param3 is 0 (the initial value), the colors are understood to be
tightly packed in the array. The initial value is 0.
_phead(_param4)
Specifies a pointer to the first component of the first color element
in the array.
.SH DESCRIPTION
_cmnd specifies the location and data format of an array of color components
to use when rendering.
_param1 specifies the number of components per color, and must be 3 or 4.
_param2 specifies the data type of each color component, and _param3
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.
(Single-array storage may be more efficient on some implementations;
see _cmnd(InterleavedArrays).)
.P
When a color array is specified,
_param1, _param2, _param3, and _param4 are saved as client-side
state.
.P
To enable and disable the color array, call _cmnd(EnableClientState) and
.br
_cmnd(DisableClientState) with the argument _const(COLOR_ARRAY). If
enabled, the color array is used when _cmnd(DrawArrays),
_cmnd(DrawElements), _cmnd(DrawRangeElements), or _cmnd(ArrayElement) is
called.
.SH NOTES
_cmnd is available only if the GL version is 1.1 or greater.
.P
The color array is initially disabled and isn't accessed when
_cmnd(ArrayElement), _cmnd(DrawArrays), _cmnd(DrawRangeElements),
or _cmnd(DrawElements) is called.
.P
Execution of _cmnd is not allowed between the execution of
_cmnd(Begin) and the corresponding execution of _cmnd(End),
but an error may or may not be generated. If no error is generated,
the operation is undefined.
.P
_cmnd is typically implemented on the client side.
.P
Color array parameters are client-side state and are therefore not saved
or restored by _cmnd(PushAttrib) and _cmnd(PopAttrib).
Use _cmnd(PushClientAttrib) and _cmnd(PopClientAttrib) instead.
.SH ERRORS
_const(INVALID_VALUE) is generated if _param1 is not 3 or 4.
.P
_const(INVALID_ENUM) is generated if _param2 is not an accepted value.
.P
_const(INVALID_VALUE) is generated if _param3 is negative.
.SH ASSOCIATED GETS
_cmnd(IsEnabled) with argument _const(COLOR_ARRAY)
.br
_cmnd(Get) with argument _const(COLOR_ARRAY_SIZE)
.br
_cmnd(Get) with argument _const(COLOR_ARRAY_TYPE)
