syslog() is printing ^I for tab

HymaNagendra · 10-24-2011, 07:42 AM

syslog(priority, "%s", string);
syslog() is printing ^I when string contains \t (tab) and printing ^M when string contains \r (carriage return).

On some systems it will convert them to "#011" and "#015".

How to print tab properly using syslog()

Do you mean printing on paper or do you mean that's what the terminal or an editor is showing?

What do you mean? Tab is an ASCII control character that means move the print head to the next tab stop. Its supported on terminals using termcap. The log device doesn't support it, so it converts it to printable characters when it is logged.

Incidentally

Code:

Unix line end = \n
MACOS = \r
MSDOS (& MSWIN) = \r\n

You don't want \r in syslog ...

The syslog messages are routed to SCSterm through serial port. On SCSterm I'm seeing ^I where ever \t is there in the log message. Do I need to change SCSterm capabilities to print the tab properly or do I need to change any setting of syslog.

That depends on whether SCSterm is receiving a tab and displaying it as ^I or receiving a ^ followed by an I. If the first, changing the SCSterm configuration would be sane ... ?
