glGetVertexAttribPointerv - OpenGL ES 3.1 Reference Pages

## Name

glGetVertexAttribPointerv — return the address of the specified generic vertex attribute pointer

## C Specification

`void glGetVertexAttribPointerv(` | GLuint index,
| GLenum pname,
| GLvoid **pointer`)`;

## Parameters

`index`

  Specifies the generic vertex attribute parameter to be returned.

`pname`

  Specifies the symbolic name of the generic vertex attribute parameter to be returned. Must be `GL_VERTEX_ATTRIB_ARRAY_POINTER`.

`pointer`

  Returns the pointer value.

## Description

`glGetVertexAttribPointerv` returns pointer information. `index` is the generic vertex attribute to be queried, `pname` is a symbolic constant indicating the pointer to be returned, and `params` is a pointer to a location in which to place the returned data.

The `pointer` returned is a byte offset into the data store of the buffer object that was bound to the `GL_ARRAY_BUFFER` target (see glBindBuffer) when the desired pointer was previously specified.

## Notes

The state returned is retrieved from the currently bound vertex array object. If the zero object is bound, the value is queried from client state.

The initial value for each pointer is 0.

## Errors

`GL_INVALID_VALUE` is generated if `index` is greater than or equal to `GL_MAX_VERTEX_ATTRIBS`.

`GL_INVALID_ENUM` is generated if `pname` is not an accepted value.

## Associated Gets

glGet with argument `GL_MAX_VERTEX_ATTRIBS`
