<H2>DESCRIPTION</H2><PRE>
|
2000-07-09 10:46:08 +08:00
|
|
|
This function uses the <B>mc5p</B> or <B>mc4</B> and <B>mc5</B> capabilities,
|
1997-05-15 12:00:00 +08:00
|
|
|
if they are present, to ship given data to a printer
|
|
|
|
|
attached to the terminal.
|
|
|
|
|
|
2000-07-09 10:46:08 +08:00
|
|
|
Note that the <B>mcprint</B> code has no way to do flow control
|
1997-05-15 12:00:00 +08:00
|
|
|
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.

<H2>RETURN VALUE</H2><PRE>
|
2000-07-09 10:46:08 +08:00
|
|
|
The <B>mcprint</B> function returns <B>ERR</B> if the write operation
|
1997-05-15 12:00:00 +08:00
|
|
|
aborted for some reason. In this case, errno will contain
|
2000-07-09 10:46:08 +08:00
|
|
|
either an error associated with <B>write(2)</B> or one of the
|
1997-05-15 12:00:00 +08:00
|
|
|
following:
|
|
|
|
|
|
|
|
|
|
ENODEV
|
|
|
|
|
Capabilities for printer redirection don't exist.
|
|
|
|
|
|
|
|
|
|
ENOMEM
|
|
|
|
|
Couldn't allocate sufficient memory to buffer the
|
|
|
|
|
printer write.
|
|
|
|
|
|
2000-07-09 10:46:08 +08:00
|
|
|
When <B>mcprint</B> succeeds, it returns the number of char-
|
1997-05-15 12:00:00 +08:00
|
|
|
acters actually sent to the printer.
