glGetVertexAttribPointerv

3G

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.

If a non-zero named buffer object was bound to the `GL_ARRAY_BUFFER` target (see

glBindBuffer

) when the desired pointer was previously specified, the `pointer` returned is a byte offset into the buffer object's data store.

## Notes

The pointer returned is client-side state.

The initial value for each pointer is 0.

## Errors

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

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

## Associated Gets

glGet

with argument `GL_MAX_VERTEX_ATTRIBS`
