void glActiveTextureARB( GLenum texture )

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-dependent value. The initial value is  GL_TEXTURE0_ARB.

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

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

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

 GL_INVALID_ENUM is generated if texture is not one of  GL_TEXTUREi_ARB,
where 0 <= i <  GL_MAX_TEXTURE_UNITS_ARB.
