.SH PARAMETERS
_phead(_param1)
Specifies the number of coordinates per array element. Must be 1, 2, 3
or 4. The initial value is 4.
_phead(_param2)
Specifies the data type of each texture coordinate.
Symbolic constants
_const(SHORT),
_const(INT),
_const(FLOAT),
or _const(DOUBLE)
are accepted. The initial value is _const(FLOAT).
_phead(_param3)
Specifies the byte offset between consecutive array elements.
If _param3 is 0, the array elements are understood 
to be tightly packed. The initial value is 0.
_phead(_param4)
Specifies a pointer to the first coordinate of the first element in the 
array.  The initial value is 0.
.SH DESCRIPTION
_cmnd specifies the location and data format of an array of texture
coordinates to use when rendering.
_param1 specifies the number of coordinates per
element, and must be 1, 2, 3, or 4.
_param2 specifies the data type of each texture coordinate
and _param3 specifies the byte stride from one
array element 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 
.br
_cmnd(InterleavedArrays).)
When a texture
coordinate array is specified, _param1, _param2, _param3, and _param4
are saved client-side state. 
.P
To enable and disable the texture coordinate array, call 
_cmnd(EnableClientState) and _cmnd(DisableClientState) with the argument
_const(TEXTURE_COORD_ARRAY). If 
enabled, the texture coordinate array is used
when _cmnd(DrawArrays), _cmnd(DrawElements), _cmnd(DrawRangeElements) or 
_cmnd(ArrayElement) is called.
.P
Use _cmnd(DrawArrays) to construct a sequence of primitives (all of the
same type) from prespecified vertex and vertex attribute arrays.
Use _cmnd(ArrayElement) to specify primitives
by indexing vertices and vertex attributes and _cmnd(DrawElements) to
construct a sequence of primitives by indexing vertices and vertex attributes.
.SH NOTES
_cmnd is available only if the GL version is 1.1 or greater.
.P
The texture coordinate array is initially disabled and it won't be
accessed when 
_cmnd(ArrayElement), _cmnd(DrawElements), _cmnd(DrawRangeElements), or
_cmnd(DrawArrays) 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 with no protocol.
.P
The texture coordinate 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.
.P
When the _arbstring(imaging) extension is supported, _cmnd updates the
texture coordinate array state of the active client texture unit,
specified with _cmnd(ClientActiveTextureARB).
.SH ERRORS
_const(INVALID_VALUE) is generated if _param1 is not 1, 2, 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.
