Name

glClientActiveTexture - select client-side active texture unit

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, 0 ≤ i < GL_MAX_TEXTURE_UNITS, 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.

Errors

GL_INVALID_ENUM is generated if texture is not one of GL_TEXTUREi, where 0 ≤ i < GL_MAX_TEXTURE_UNITS.

Notes

It is always the case that GL_TEXTUREi = GL_TEXTURE0 + i.

Associated Gets

glGet with argument GL_MAX_TEXTURE_UNITS
