glClientActiveTextureARB(3)

NAME

       glClientActiveTextureARB - select active texture unit

C SPECIFICATION

       void glClientActiveTextureARB( 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  implementation-
                dependent value.  The initial value is GL_TEXTURE0_ARB.

DESCRIPTION

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

NOTES

       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.

ERRORS

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