Имя (Name)

mcprint - ship binary data to printer

---

Синопсис (Synopsis)

#include <curses.h>

       int mcprint(char *data, int len);

---

Описание (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.

Возвращаемое значение (Return value)

The mcprint function returns ERR if the write operation aborted
       for some reason.  In this case, errno will contain either an
       error associated 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.

---

Портативность (Portability)

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

Ошибки (баги) (Bugs)

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