GLTEXCOORDPOINTER(3G)		 OpenGL Manual		 GLTEXCOORDPOINTER(3G)

NAME
       glTexCoordPointer - define an array of texture coordinates

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

PARAMETERS
       size
	   Specifies the number of coordinates per array element. Must be 1,
	   2, 3, or 4. The initial value is 4.

       type
	   Specifies the data type of each texture coordinate. Symbolic
	   constants GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted.
	   The initial value is GL_FLOAT.

       stride
	   Specifies the byte offset between consecutive texture coordinate
	   sets. If stride is 0, the array elements are understood to be
	   tightly packed. The initial value is 0.

       pointer
	   Specifies a pointer to the first coordinate of the first texture
	   coordinate set in the array. The initial value is 0.

DESCRIPTION
       glTexCoordPointer specifies the location and data format of an array of
       texture coordinates to use when rendering.  size specifies the number
       of coordinates per texture coordinate set, and must be 1, 2, 3, or 4.
       type specifies the data type of each texture coordinate, and stride
       specifies the byte stride from one texture coordinate set 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 glInterleavedArrays().)

       If a non-zero named buffer object is bound to the GL_ARRAY_BUFFER
       target (see glBindBuffer()) while a texture coordinate 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 texture coordinate vertex array client-side state
       (GL_TEXTURE_COORD_ARRAY_BUFFER_BINDING).

       When a texture coordinate 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 a texture coordinate array, call
       glEnableClientState() and glDisableClientState() with the argument
       GL_TEXTURE_COORD_ARRAY. If enabled, the texture coordinate array is
       used when glArrayElement(), glDrawArrays(), glMultiDrawArrays(),
       glDrawElements(), glMultiDrawElements(), or glDrawRangeElements() is
       called.

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

       For OpenGL versions 1.3 and greater, or when the ARB_multitexture
       extension is supported, glTexCoordPointer updates the texture
       coordinate array state of the active client texture unit, specified
       with glClientActiveTexture().

       Each texture coordinate array is initially disabled and isn't accessed
       when glArrayElement(), glDrawElements(), glDrawRangeElements(),
       glDrawArrays(), glMultiDrawArrays(), or glMultiDrawElements() is
       called.

       Execution of glTexCoordPointer 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.

       glTexCoordPointer is typically implemented on the client side.

       Texture coordinate 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 1, 2, 3, or 4.

       GL_INVALID_ENUM is generated if type is not an accepted value.

       GL_INVALID_VALUE is generated if stride is negative.
