C Specification
void glClientActiveTexture
GLenum texture
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_TEXTUREi,
where i ranges from 0 to the value of GL_MAX_TEXTURE_COORDS - 1, which is an
implementation-dependent value. The initial value is
GL_TEXTURE0.
Description
glClientActiveTexture 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.
Notes
glClientActiveTexture is supported only if the GL version is 1.3 or greater, or
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,
where
i ranges from 0 to the value of GL_MAX_TEXTURE_COORDS - 1.
Associated Gets
glGet with argument GL_CLIENT_ACTIVE_TEXTURE or GL_MAX_TEXTURE_COORDS
