GLCLIENTACTIVETEXTUREARB(3G) GLCLIENTACTIVETEXTUREARB(3G)
NAME
glClientActiveTextureARB - select active texture unit
C SPECIFICATION
void glClientActiveTextureARB( 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_ARB where 0 <= i < GL_MAX_TEXTURE_UNITS_ARB, which is an implementation-dependent value. The
initial value is GL_TEXTURE0_ARB.
DESCRIPTION
glClientActiveTextureARB 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
glClientActiveTextureARB 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_TEXTUREi_ARB, where 0 <= i < GL_MAX_TEXTURE_UNITS_ARB.
