Question

How does one idiomatically “pop” from the start of a singly-linked list in GLib? There are several functions that can be glued together but don’t stand out as the intended inverse of g_slist_prepend.

Answer 1

Depending on your use case, either

// pop and discard head
list = g_slist_delete_link(list, list);

or

// pop head but keep it for further use
GSList *head = list;
list = g_slist_remove_link(list, head);
// do stuff with head
g_slist_free1(head);
