# glBindBufferRange

bind a range within a buffer object to an indexed buffer target

## C Specification

                    void glBindBufferRange
                    GLenumtarget
                    GLuintindex
                    GLuintbuffer
                    GLintptroffset
                    GLsizeiptrsize

## Parameters

`target`

  Specify the target of the bind operation. `target` must be one of `GL_ATOMIC_COUNTER_BUFFER`, `GL_TRANSFORM_FEEDBACK_BUFFER`, `GL_UNIFORM_BUFFER`, or `GL_SHADER_STORAGE_BUFFER`.

`index`

  Specify the index of the binding point within the array specified by `target`.

`buffer`

  The name of a buffer object to bind to the specified binding point.

`offset`

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

`size`

  The amount of data in machine units that can be read from the buffet object while used as an indexed target.

## Description

`glBindBufferRange` binds a range the buffer object `buffer` represented by `offset` and `size` to the binding point at index `index` of the array of targets specified by `target`. Each `target` represents an indexed array of buffer binding points, as well as a single general binding point that can be used by other buffer manipulation functions such as glBindBuffer or glMapBuffer. In addition to binding a range of `buffer` to the indexed buffer binding target, `glBindBufferRange` also binds the range to the generic buffer binding point specified by `target`.

`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

The `GL_ATOMIC_COUNTER_BUFFER` target is available only if the GL version is 4.2 or greater.

The `GL_SHADER_STORAGE_BUFFER` target is available only if the GL version is 4.3 or greater.

## Errors

`GL_INVALID_ENUM` is generated if `target` is not one of `GL_ATOMIC_COUNTER_BUFFER`, `GL_TRANSFORM_FEEDBACK_BUFFER`, `GL_UNIFORM_BUFFER` or `GL_SHADER_STORAGE_BUFFER`.

`GL_INVALID_VALUE` is generated if `index` is greater than or equal to the number of `target`-specific indexed binding points.

`GL_INVALID_VALUE` is generated if `size` is less than or equal to zero, or if `offset` + `size` is greater than the value of `GL_BUFFER_SIZE`.

Additional errors may be generated if `offset` violates any `target`-specific alignmemt restrictions.
