Status
XGetCommand(display, w, argv_return, argc_return)

>>ASSERTION Good A
When the WM_COMMAND property is set for the window
.A w ,
is of
.M type
STRING, and is of
.M format
8, then a call to xname returns the property string list,
which can be freed with XFree,
in the
.A argv_return
argument and the number of strings in the
.A argc_return
argument and returns non-zero.
>>STRATEGY
Set the WM_COMMAND property using XSetCommand.
Obtain the value of the WM_COMMAND property using XGetCommand.
Verify that the call did not return zero.
Verify that the number and value of the returned strings is correct.
