Function

GLibdatalist_foreach

Declaration 

void
g_datalist_foreach (
  GData** datalist,
  GDataForeachFunc func,
  gpointer user_data
)

Description

Calls the given function for each data element of the datalist. The function is called with each data element’s GQuark id and data, together with the given user_data parameter. Note that this function is NOT thread-safe. So unless datalist can be protected from any modifications during invocation of this function, it should not be called.

func can make changes to datalist, but the iteration will not reflect changes made during the g_datalist_foreach() call, other than skipping over elements that are removed.
