hi john:
i have found the answer in http://www.xfree86.org/4.2.1/XChangeProperty.3.html
-------->
The lifetime of a property is not tied to the storing client. Properties remain until explicitly deleted, until the window is destroyed, or until the server resets.

hi,John
thank you very much ,
but i have another question,
I've found that 'data' has been allocated some memory
with g_malloc() and i can't find where it was freed,
can XChangeProperty() free the memory ?

data = "" (total_size);

The "header" variable is equal to "data" (though a different type), and is passed to XChangeProperty() a little further down the code. > >John
