foreachRemove
Calls the given function for each key/value pair in the #GHashTable. If the function returns true, then the key/value pair is removed from the #GHashTable. If you supplied key or value destroy functions when creating the #GHashTable, they are used to free the memory allocated for the removed keys and values.
See #GHashTableIter for an alternative way to loop over the key/value pairs in the hash table.
Return
the number of key/value pairs removed
Parameters
hashTable
a #GHashTable
func
