int PL_atom_mbchars(atom_t
atom, size_t len, char *s, unsigned int flags)This function generalizes fetching the text associated with an atom. The
encoding depends on the flags REP_UTF8, REP_MB
or REP_ISO_LATIN_1. Storage is defined by the BUF_*
flags as described with PL_get_chars().
The flag CVT_EXCEPTION defines whether or not the function
fails silently or raises a Prolog exception. This function may fail
because atom is not a text atom but a blob (see section
12.4.9), conversion to the requested encoding is not possible or a
resource error occurs.
