Availability:C-language interface function
int PL_for_dict(term_t
dict, int (*func)(term_t key, term_t value, void *closure), void
*closure, int flags)Iterates over dict, calling func for each item. In
each call, key and value are the processed item's
key-value pair and the closure argument is passed from the
call to
PL_for_dict().
If func returns a non-0 value, the iteration
stops and PL_for_dict()
returns that value; otherwise, all pairs are processed and PL_for_dict()
returns 0. If
flags contains PL_FOR_DICT_SORTED, the key-value
pairs are processed in the standard order of terms; otherwise the
processing order is unspecified.
