# glTransformFeedbackBufferRange

## Name

glTransformFeedbackBufferRange — bind a range within a buffer object to a transform feedback buffer object

## C Specification

`void glTransformFeedbackBufferRange(` | GLuint xfb,
| GLuint index,
| GLuint buffer,
| GLintptr offset,
| GLsizei size`)`;

## 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.

`offset`

  The starting offset in basic machine units into the buffer object.

`size`

  The amount of data in basic machine units that can be read from or written to the buffer object while used as an indexed target.

## Description

`glTransformFeedbackBufferRange` binds a range of the buffer object `buffer` represented by `offset` and `size` to the binding point at index `index` of the transform feedback object `xfb`.

`offset` specifies the offset in basic machine units into the buffer object `buffer` and `size` specifies the amount of data that can be read from the buffer object while used as an indexed target.

## Notes

## 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`).

`GL_INVALID_VALUE` is generated if `offset` is negative.

`GL_INVALID_VALUE` is generated if `buffer` is non-zero and either `size` is less than or equal to zero, or `offset` + `size` is greater than the value of `GL_BUFFER_SIZE` for `buffer`.
