C SPECIFICATION

       void GLAPIENTRY glActiveTextureARB( GLenum texture )

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_TEXTUREi_ARB, where 0 <= i
                < GL_MAX_TEXTURE_UNITS_ARB, which is an  implementation-depen-
                dent value.  The intial 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_TEXTUREi_ARB,
       where 0 <= i < GL_MAX_TEXTURE_UNITS_ARB.
