12.4.7 Serializing and deserializing Prolog terms
- int PL_put_term_from_chars(term_t t, int flags, size_t len, const char *s)
- Parse the text from the C-string s holding len
bytes and put the resulting term in t. len can be
(size_t)-1, assuming a 0-terminated string. The flags argument controls the encoding and is currently one ofREP_UTF8(string is UTF8 encoded),REP_MB(string is encoded in the current locale) or 0 (string is encoded in ISO latin 1). The string may, but is not required, to be closed by a full stop (.).If parsing produces an exception the behaviour depends on the
CVT_EXCEPTIONflag. If present, the exception is propagated into the environment. Otherwise, the exception is placed in t and the return value isFALSE.195TheCVT_EXCEPTIONwas added in version 8.3.12.
