This module defines several new object types and functions that provide access to the functionality of the Standard Window System Interface, STDWIN [CWI report CR-R8817]. It is available on systems to which STDWIN has been ported (which is most systems). It is only available if the <#4#>DISPLAY<#4#> environment variable is set or an explicit <#666#>-display <#5#>displayname<#5#><#666#> argument is passed to the interpreter.
Functions have names that usually resemble their C STDWIN counterparts with the initial `w' dropped. Points are represented by pairs of integers; rectangles by pairs of points. For a complete description of STDWIN please refer to the documentation of STDWIN for C programmers (aforementioned CWI report).
