glXImportContextEXT()
NAME
  glXImportContextEXT - import another process's indirect rendering context.

SYNOPSIS
  GLXContext glXImportContextEXT(
	  Display *dpy,
	  GLXContextID contextID );

PARAMETERS
  dpy Specifies the connection to the X server.

  contextID
      Specifies a GLX rendering context.

DESCRIPTION
  glXImportContextEXT() creates a GLXContext given the XID of an existing
  GLXContext. It may be used in place of glXCreateContext(), to share another
  process's indirect rendering context.

  Only the server-side context information can be shared between X clients;
  client-side state, such as pixel storage modes, cannot be shared. Thus,
  glXImportContextEXT() must allocate memory to store client-side
  information.	This memory is freed by calling glXFreeContextEXT().

  This call does not create a new XID.	It merely makes an existing object
  available to the importing client (Display *). Like any XID, it goes away
  when the creating client drops its connection or the ID is explicitly
  deleted.  Note that this is when the XID goes away. The object goes away
  when the XID goes away AND the context is not current to any thread.

  If contextID refers to a direct rendering context then no error is
  generated but glXImportContextEXT() returns NULL.

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

ERRORS
  GLXBadContext is generated if contextID does not refer to a valid context.
