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


</PRE><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>*</STRONG><EM>data</EM><STRONG>,</STRONG> <STRONG>int</STRONG> <EM>len</EM><STRONG>);</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,  <STRONG>errno</STRONG>  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.

       Padding in the <STRONG>mc5p</STRONG>, <STRONG>mc4</STRONG> and <STRONG>mc5</STRONG> capabilities will not be interpreted.
