+ *
+ * As with most UNIX tools, this function will return the value of the

+ * name, falling back to the `passwd` file in the case that it is unset.
+ *
+ * If the path given in `HOME` is non-absolute, does not exist, or is
+ * not a directory, the result is undefined.
+ *
+ * Before version 2.36 this function would ignore the `HOME` environment
+ * variable, taking the value from the `passwd` database instead. This was
+ * changed to increase the compatibility of GLib with other programs (and
+ * the XDG basedir specification) and to increase testability of programs
+ * based on GLib (by making it easier to run them from test frameworks).
+ *
+ * If your program has a strong requirement for either the new or the
+ * old behaviour (and if you don't wish to increase your GLib
+ * dependency to ensure that the new behaviour is in effect) then you
+ * should either directly check the `HOME` environment variable yourself
+ * or unset it before calling any functions in GLib.
