glGetVertexAttribPointerv : PyOpenGL 3.1.4 GL Man Pages

return the address of the specified generic vertex attribute pointer

Signature

glGetVertexAttribPointerv( GLuint ( index ) , GLenum ( pname ) , void **( pointer ) )-> void

glGetVertexAttribPointerv( index , pname , pointer )

Parameters

Variables	Description
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.

The initial value for each pointer is 0.

Errors

GL_INVALID_OPERATION is generated if no vertex array object is currently bound.

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
