C SPECIFICATION
void glActiveTextureARB( GLenum texture )
PARAMETERS
texture Specifies which texture unit to make active. The number of
texture units is implementation dependent, but must be
atlease 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.
DESCRIPTIONglActiveTextureARB selects which texture unit subsequent texture state
calls will affect. The number of texture units an implementation sup‐
ports is implementation dependent, but must be atlease two.
Vertex arrays are client-side GL resources, which are selected by the
glClientActiveTextureARB routine.
NOTESglActiveTextureARB is only supported if GL_ARB_multitexture is included
in the string returned by glGetString when called with the argument
GL_EXTENSIONS.
ERRORS
GL_INVALID_ENUM is generated if texture is not one of GL_TEXTUREi_ARB,
where 0<=i<GL_MAX_TEXTURE_UNITS_ARB.
