C SPECIFICATION

10       void glActiveTextureARB( GLenum texture )

12       delim $$
13

PARAMETERS

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

DESCRIPTION

22       glActiveTextureARB  selects which texture unit subsequent texture state
23       calls will affect.  The number of texture units an implementation  sup‐
24       ports is implementation dependent, but must be at least 2.
25
26       Vertex  arrays  are client-side GL resources, which are selected by the
27       glClientActiveTextureARB routine.

NOTES

30       glActiveTextureARB is only supported if GL_ARB_multitexture is included
31       in  the  string  returned  by glGetString when called with the argument
32       GL_EXTENSIONS.
33

ERRORS

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