 * @new_str: (nullable): a string to assign to @str_pointer

 *

 * Updates a pointer to a string to a copy of @new_str and returns whether the

 * string was changed.

 *

 * If @new_str matches the previous string, this function is a no-op. If

 * @new_str is different, a copy of it will be assigned to @str_pointer and

 * the previous string pointed to by @str_pointer will be freed with

 * [func@GLib.free].

 *

 * @str_pointer must not be `NULL`, but can point to a `NULL` value.

 *

 * One convenient usage of this function is in implementing property settings:

 * ```C

 * void

 * foo_set_bar (Foo        *foo,

 *              const char *new_bar)

 * {

 *   g_return_if_fail (IS_FOO (foo));

 *

 *   if (g_set_str (&foo->bar, new_bar))

 *     g_object_notify (foo, "bar");

 * }

 * ```

 *

 * Returns: true if the value of @str_pointer changed, false otherwise

 *

 * Since: 2.76
