|
|
* https://gitlab.gnome.org/GNOME/libgweather/-/blob/main/libgweather/tests/test_libgweather.c
|
|
* and only adapted to my needs.
|
|
* It starts with the offline gweather world location and iterates through every child.
|
|
* If the child type is not a city it recursively calls itself again to iterate through this child.
|
|
* If the next_child is not existent == NULL the while loop breaks.
|
|
* If the child type is a city and contains the search string (needle) it adds this city to the
|
|
* locations array.
