Function

GLibListappend

Declaration

GList*
g_list_append (
  GList* list,
  gpointer data
)

Description

Adds a new element on to the end of the list.

Note that the return value is the new start of the list, if list was empty; make sure you store the new value.

g_list_append() has to traverse the entire list to find the end, which is inefficient when adding multiple elements. A common idiom to avoid the inefficiency is to use g_list_prepend() and reverse the list with g_list_reverse() when all elements have been added.

// Notice that these are initialized to the empty list.
GList *string_list = NULL, *number_list = NULL;

// This is a list of strings.
string_list = g_list_append (string_list, "first");
string_list = g_list_append (string_list, "second");

// This is a list of integers.
number_list = g_list_append (number_list, GINT_TO_POINTER (27));
number_list = g_list_append (number_list, GINT_TO_POINTER (14));
