GLCLIENTACTIVETEXTUREARB

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_TEXTURE img _ARB where 0 ≤ Image grohtml-19360-3.png < 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_TEXTURE img _ARB, where 0 ≤ Image grohtml-19360-5.png < GL_MAX_TEXTURE_UNITS_ARB.
