- int Sferror(IOSTREAM
*s)
- Returns
TRUE if the stream is in an error condition,
FALSE if the stream is valid and in normal condition and -1
if the stream is invalid.
- void Sclearerr(IOSTREAM
*s)
- Clear the error state of a stream. This includes the end-of-file state,
pending warnings and errors and timeout.
- int Sseterr(IOSTREAM
*s, int which, const char *message)
- Set an error or warning state on the stream. The which
argument is one of
SIO_WARN or SIO_FERR. This
causes PL_release_stream()
to print a message (SIO_WARN) or raise an exception (SIO_FERR).
- int Sset_exception(IOSTREAM
*s, term_t ex)
- Associate a Prolog exception term with the stream or clear the
associated exception if ex is 0 and set/clear the
SIO_FERR condition on the stream. If an exception is
assocated PL_release_stream()
raises this exception.
