>>EXTERN
#include "Xatom.h"
static XTextProperty textprop = { (unsigned char *) 0, XA_STRING, 8, (unsigned long) 0 };
>>ASSERTION Good A
When the WM_NAME property
exists on the window specified by the
.A w
argument, then a call to xname stores
the data, which can be freed with
.S XFree ,
in the
.M value
field, the type of the data in the
.M encoding
field, the format of the data in the
.M format
field, and the number of items of data in the
.M nitems
field of the
.S XTextProperty
structure named by the
.A text_prop_return
argument and returns non-zero.
>>STRATEGY
Create a window with XCreateWindow.
Set the property WM_NAME for the window with XSetWMName.
Obtain the value of the WM_NAME property with XGetWMName.
Verify that the encoding, format, value and nitems fields of the returned structure are correct.
Release the allocated memory using XFree.

>>ASSERTION Good A
When the WM_NAME property
does not exist on the window
specified by the
.A w
argument, then a call to xname sets the
.M value
field to NULL, the
.M encoding
field to None, the
.M format
field to 0 and the
.M nitems
field to 0 of the
.S XTextProperty
structure named by the
.A text_prop_return
argument and returns zero.
>>STRATEGY
Create a window with XCreateWindow
Get the value of the unset property WM_NAME with XGetWMName
Verify that the call returned False
Verify that in the returned XTextProperty structure the encoding field was none,
the format component was 0, the nitems component was 0 and the
value component was NULL.
