- <STRONG>mcprint</STRONG> - ship binary data to printer
-
-
-</PRE>
-<H2>SYNOPSIS</H2><PRE>
- <STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
-
- <STRONG>int</STRONG> <STRONG>mcprint(char</STRONG> <STRONG>*data,</STRONG> <STRONG>int</STRONG> <STRONG>len);</STRONG>
-
-
-</PRE>
-<H2>DESCRIPTION</H2><PRE>
- This function uses the <STRONG>mc5p</STRONG> or <STRONG>mc4</STRONG> and <STRONG>mc5</STRONG> capabilities,
- if they are present, to ship given data to a printer
- attached to the terminal.
-
- Note that the <STRONG>mcprint</STRONG> code has no way to do flow control
- with the printer or to know how much buffering it has.
- Your application is responsible for keeping the rate of
- writes to the printer below its continuous throughput rate
- (typically about half of its nominal cps rating). Dot-
- matrix printers and 6-page-per-minute lasers can typically
- handle 80cps, so a good conservative rule of thumb is to
- sleep for a second after shipping each 80-character line.
-

-</PRE>
-<H2>RETURN VALUE</H2><PRE>
- The <STRONG>mcprint</STRONG> function returns <STRONG>ERR</STRONG> if the write operation
- aborted for some reason. In this case, errno will contain
- either an error associated with <STRONG>write(2)</STRONG> or one of the
- following:
-
- ENODEV
- Capabilities for printer redirection don't exist.
-
- ENOMEM
- Couldn't allocate sufficient memory to buffer the
- printer write.
-
- When <STRONG>mcprint</STRONG> succeeds, it returns the number of char-
- acters actually sent to the printer.
-
-
-</PRE>
-<H2>PORTABILITY</H2><PRE>
- The <STRONG>mcprint</STRONG> call was designed for <STRONG><A HREF="ncurses.3x.html">ncurses(3X)</A></STRONG>, and is not
- found in SVr4 curses, 4.4BSD curses, or any other previous
- version of curses.
-
-
-</PRE>
-<H2>BUGS</H2><PRE>
- Padding in the <STRONG>mc5p</STRONG>, <STRONG>mc4</STRONG> and <STRONG>mc5</STRONG> capabilities will not be
- interpreted.
