# glXFreeContextEXT

free client-side memory for imported context

## C Specification

                    void glXFreeContextEXT
                    Display * dpy
                    GLXContext ctx

## Parameters

`dpy`

  Specifies the connection to the X server.

`ctx`

  Specifies a GLX rendering context.

## Description

`glXFreeContextEXT` frees the client-side part of a GLXContext that was created with glXImportContextEXT. `glXFreeContextEXT` does not free the server-side context information or the XID associated with the server-side context.

`glXFreeContextEXT` is part of the `EXT_import_context` extension, not part of the core GLX command set. If _glxextstring(EXT_import_context) is included in the string returned by glXQueryExtensionsString, when called with argument `GLX_EXTENSIONS`, extension `EXT_vertex_array` is supported.

## Errors

`GLXBadContext` is generated if `ctx` does not refer to a valid context.
