GLCLIENTACTIVETEXTUREARB(3G)GLCLIENTACTIVETEXTUREARB(3G)NAMEglClientActiveTextureARB - 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.
DESCRIPTIONglClientActiveTextureARB 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.
NOTESglClientActiveTextureARB 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.
