Synopsis:

#include <screen/screen.h>
int screen_get_window_property_cv(screen_window_t win,
                                  int pname,
                                  int len,
                                  char *param)

Arguments:

win

pname
The name of the property whose value is being queried. The properties available for querying are of type Screen property types.
len
