GLXDrawable glXGetCurrentReadDrawable( void )
The glXGetCurrentReadDrawable subroutine returns the current read drawable, as specified by the glXMakeContextCurrent subroutine. If the glXMakeCurrent subroutine is used, then the specified drawable is both the read and write drawable. If there is no current read drawable, None is returned.
This subroutine returns client-side information only. It does not make a round-trip to the server.
