       <STRONG>mcprint</STRONG> - ship binary data to printer

<H2><a name="h2-SYNOPSIS">SYNOPSIS</a></H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>

       <STRONG>int</STRONG> <STRONG>mcprint(char</STRONG> <STRONG>*data,</STRONG> <STRONG>int</STRONG> <STRONG>len);</STRONG>


</PRE>
<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></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><a name="h2-RETURN-VALUE">RETURN VALUE</a></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 do not exist.

       ENOMEM
            Couldn't  allocate  sufficient  memory  to buffer the
            printer write.

       When <STRONG>mcprint</STRONG> succeeds, it returns the number of characters
       actually sent to the printer.


</PRE>
<H2><a name="h2-PORTABILITY">PORTABILITY</a></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.

<H2><a name="h2-BUGS">BUGS</a></H2><PRE>
       Padding  in the <STRONG>mc5p</STRONG>, <STRONG>mc4</STRONG> and <STRONG>mc5</STRONG> capabilities will not be
       interpreted.
