NAME
       glActiveTextureARB - select active texture unit


C SPECIFICATION
       void glActiveTextureARB( GLenum texture )

       delim $$

PARAMETERS
       texture	Specifies  which  texture  unit to make active. The number of
		texture units is implementation dependent,  but	 must  be  at
		least  two. texture must be one of GL_TEXTURE$i$_ARB, where 0
		≤ $ i $ < GL_MAX_TEXTURE_UNITS_ARB, which is  an  implementa-
		tion-dependent	value.	The initial value is GL_TEXTURE0_ARB.

DESCRIPTION
       glActiveTextureARB selects which texture unit subsequent texture state
       calls will affect.  The number of texture units an implementation sup-
       ports is implementation dependent, but must be at least 2.

       Vertex arrays are client-side GL resources, which are selected by  the
       glClientActiveTextureARB routine.

NOTES
       glActiveTextureARB   is	 only  supported  if  GL_ARB_multitexture  is
       included in the string returned by glGetString when  called  with  the
       argument GL_EXTENSIONS.

ERRORS
       GL_INVALID_ENUM	  is   generated   if	texture	  is   not   one   of
       GL_TEXTURE$i$_ARB,
       where 0 ≤ $ i $ < GL_MAX_TEXTURE_UNITS_ARB.
