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. +. +.SH RETURN VALUE +The \fBmcprint\fR function returns \fBERR\fR if the write operation aborted +for some reason. In this case, errno will contain either an error associated +with \fBwrite\fP(2) or one of the following: +.TP 5 +ENODEV +Capabilities for printer redirection do not exist. +.TP 5 +ENOMEM +Couldn't allocate sufficient memory to buffer the printer write. +.PP +When \fBmcprint\fR succeeds, it returns the number of characters actually +sent to the printer. +.SH PORTABILITY +The \fBmcprint\fR call was designed for \fBncurses\fR(3NCURSES), and is not found +in SVr4 curses, 4.4BSD curses, or any other previous version of curses. +.SH BUGS +Padding in the \fBmc5p\fR, \fBmc4\fR and \fBmc5\fR capabilities will not be +interpreted. +.SH SEE ALSO +\fBncurses\fR(3NCURSES) |
