NAME
       mcprint - ship binary data to printer

SYNOPSIS
       #include <curses.h>

       int mcprint(char *data, int len);

DESCRIPTION
       This function uses the mc5p or mc4 and mc5 capabilities, if they are present, to ship given data to a printer attached to the terminal.

       Note  that  the	mcprint  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.

RETURN VALUE
       The mcprint function returns ERR if the write operation aborted for some reason.  In this case, errno will contain either an error  associ-
       ated with write(2) 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 mcprint succeeds, it returns the number of characters actually sent to the printer.

PORTABILITY
       The  mcprint  call  was	designed  for  ncurses(3NCURSES), and is not found in SVr4 curses, 4.4BSD curses, or any other previous version of
       curses.

BUGS
       Padding in the mc5p, mc4 and mc5 capabilities will not be interpreted.
