DESCRIPTION
These routines write the indicated the cstream stream, guarenteeing that no lines are longer than some fixed length.
Most of these routines have a name from wnwtok with a "_pretty" suffix tacked on. These routines do the same thing as the corresponding wnwtok routine, except that an extra linefeed is output if writing the specified object first would exceed the line length limit.
Enclosing write calls from wnwtok or wnwtokp between wn_start_pretty_block and wn_end_pretty_block causes these calls to be treated as a unit when deciding whether to output an extra linefeed. Outermost wn_start_pretty_block and wn_end_pretty_block calls take precedence over inner wn_start_pretty_block and wn_end_pretty_block calls.
wn_set_pretty_linefeed_routine causes *ppretty_linefeed_routine to be used for outputing extra linefeeds for cstream stream. This might be useful if a continuation character or a tab is desired with such linefeeds. The default is to use wn_write_linefeed.
wn_set_line_length_limit sets the line length limit of stream to len. The default is 80.
wn_write_linefeed writes a linefeed to stream and makes a note of the linefeed's mark. This is NOT the same as issuing a
wn_write_char(stream,'n');
wn_write_char makes no note of the linefeed's mark; thus the line length and column number will still be computed from the last wn_write_linefeed.
