GLTEXCOORDPOINTER(3G)					 GLTEXCOORDPOINTER(3G)

NAME
       glTexCoordPointer - define an array of texture coordinates

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

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  array  elements.
	       If stride is 0, the array elements are understood to be tightly
	       packed. The initial value is 0.

       ptr     Specifies a pointer to the first coordinate of the  first  ele‐
	       ment in the array.  The initial value is 0.

DESCRIPTION
       glTexCoordPointer  specifies the location and data  of an array of tex‐
       ture coordinates to use when rendering.	size specifies the  number  of
       coordinates per element, 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  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 implemen‐
       tations; see
       glInterleavedArrays.)  When a texture coordinate	 array	is  specified,
       size, type, stride, and ptr are saved client-side state.

       To   enable   and   disable   the   texture   coordinate	  array,  call
       glEnableClientState  and	  glDisableClientState	 with	the   argument
       GL_TEXTURE_COORD_ARRAY.	If  enabled,  the  texture coordinate array is
       used  when   glDrawArrays,   glDrawElements,   glDrawRangeElements   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
       glArrayElement  to  specify  primitives by indexing vertices and vertex
       attributes and glDrawElements to construct a sequence of primitives  by
       indexing vertices and vertex attributes.

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

       The texture coordinate array is initially  disabled  and	 it  won't  be
       accessed	 when  glArrayElement, glDrawElements, glDrawRangeElements, or
       glDrawArrays 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	 unde‐
       fined.

       glTexCoordPointer  is  typically implemented on the client side with no
       protocol.

       The texture coordinate array parameters are client-side state  and  are
       therefore  not  saved or restored by glPushAttrib and glPopAttrib.  Use
       glPushClientAttrib and glPopClientAttrib instead.

       When  the  GL_ARB_imaging  extension  is	 supported,  glTexCoordPointer
       updates the texture coordinate array state of the active client texture
       unit, specified with glClientActiveTextureARB.

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.

       glGet with argument GL_TEXTURE_COORD_ARRAY_SIZE
       glGet with argument GL_TEXTURE_COORD_ARRAY_TYPE
