glClientActiveTextureARB - select active texture unit

void glClientActiveTextureARB( GLenum 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.










glClientActiveTextureARB selects the vertex array client
    state parameters to be modified by glTexCoordPointer, and enabled or
    disabled with glEnableClientState or glDisableClientState,
    respectively, when called with a parameter of
  GL_TEXTURE_COORD_ARRAY.








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


glClientActiveTextureARB sets
    GL_CLIENT_ACTIVE_TEXTURE_ARB to the active texture unit.








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