glBindTextureUnit - OpenGL 4 Reference Pages

## Name

glBindTextureUnit — bind an existing texture object to the specified texture unit

## C Specification

`void glBindTextureUnit(` | GLuint unit,
| GLuint texture`)`;

## Parameters

`unit`

  Specifies the texture unit, to which the texture object should be bound to.

`texture`

  Specifies the name of a texture.

## Description

`glBindTextureUnit` binds an existing texture object to the texture unit numbered `unit`.

`texture` must be zero or the name of an existing texture object. When `texture` is the name of an existing texture object, that object is bound to the target, in the corresponding texture unit, that was specified when the object was created. When `texture` is zero, each of the targets enumerated at the beginning of this section is reset to its default texture for the corresponding texture image unit.

## Associated Gets

glGet with argument `GL_TEXTURE_BINDING_1D`, `GL_TEXTURE_BINDING_2D`, `GL_TEXTURE_BINDING_3D`, `GL_TEXTURE_BINDING_1D_ARRAY`, `GL_TEXTURE_BINDING_2D_ARRAY`, `GL_TEXTURE_BINDING_RECTANGLE`, `GL_TEXTURE_BINDING_BUFFER`, `GL_TEXTURE_BINDING_CUBE_MAP`, `GL_TEXTURE_BINDING_CUBE_MAP_ARRAY`, `GL_TEXTURE_BINDING_2D_MULTISAMPLE` or `GL_TEXTURE_BINDING_2D_MULTISAMPLE_ARRAY`.

## Errors

`GL_INVALID_OPERATION` error is generated if `texture` is not zero or the name of an existing texture object.
