# glTransformFeedbackBufferBase

## Name

glTransformFeedbackBufferBase — bind a buffer object to a transform feedback buffer object

## C Specification

`void glTransformFeedbackBufferBase(` | GLuint xfb,
| GLuint index,
| GLuint buffer`)`;

## Parameters

`xfb`

  Name of the transform feedback buffer object.

`index`

  Index of the binding point within `xfb`.

`buffer`

  Name of the buffer object to bind to the specified binding point.

## Description

`glTransformFeedbackBufferBase` binds the buffer object `buffer` to the binding point at index `index` of the transform feedback object `xfb`.

## Notes

Calling `glTransformFeedbackBufferBase` is equivalent to calling glTransformFeedbackBufferRange with `offset` zero and `size` equal to the size of `buffer`.

## Errors

`GL_INVALID_OPERATION` is generated if `xfb` is not the name of an existing transform feedback object.

`GL_INVALID_VALUE` is generated if in `buffer` is not zero or the name of an existing buffer object.

`GL_INVALID_VALUE` is generated if `index` is greater than or equal to the number of transform feedback buffer binding points (the value of `GL_TRANSFORM_FEEDBACK_BUFFER_BINDING`).
