NAME

       glActiveTexture - select active texture unit

C SPECIFICATION

       void glActiveTexture(GLenum texture);

PARAMETERS

       texture
           Specifies which texture unit to make active. The number of texture units is
           implementation dependent, but must be at least 80.  texture must be one of
           GL_TEXTUREi, where i ranges from 0 (GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1). The
           initial value is GL_TEXTURE0.

DESCRIPTION

       glActiveTexture 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 80.

ERRORS

       GL_INVALID_ENUM is generated if texture is not one of GL_TEXTUREi, where i ranges from 0
       to (GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS - 1).

ASSOCIATED GETS

       glGet() with argument GL_ACTIVE_TEXTURE, or GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
