An error + must be thrown. + + * stream.c (unimpl, unimpl_put_string, unimpl_put_char, + unimpl_put_byte, unimpl_get_line, unimpl_get_char, unimpl_get_byte, + unimpl_unget_char, unimpl_unget_byte, unimpl_seek, null_put_string, + null_put_char, null_put_byte, null_get_line, null_get_char, + null_get_byte, null_close, null_flush, null_seek, null_set_prop, + null_get_error, null_get_error_str, null_clear_error): New + static functions. + (fill_stream_ops): New function. + (null_ops): Use null_put_string, etc., instead of null pointers. + (stdio_clear_error, dir_clear_error, cat_clear_error): Return value now + indicating whether an error was cleared. + (stream_set_prop, stream_get_prop, real_time_stream_p, close_stream, + get_error, get_error_str, clear_error, get_line, get_char, get_byte, + unget_char, unget_byte, put_string, put_char, put_byte, + flush_stream): Do not test whether a function in the ops table + is defined; just call it, and return its value. + (stream_init): Call fill_stream_ops on all stream operation + structures so any null pointers are defaulted to appropriate + functions. + + * stream.h (struct strm_ops): clear_error gets return value. + (fill_stream_ops): Declared. + + * syslog.c (syslog_init): Call fill_stream_ops on syslog_strm_ops. + 2015-07-04 Kaz Kylheku <kaz@kylheku.com> Reduce regex duplication in genvim.txr. |
