Writing logging to screen

Hi,

How do I run lldb in such way that the logging statements are visible on my stdout/stderr?

For example, I'm trying to debug:

void
ReadRegOperation::Execute(ProcessMonitor *monitor)
{
     Log *log (ProcessPOSIXLog::GetLogIfAllCategoriesSet (POSIX_LOG_REGISTERS));

<snip>

     if (log)
         log->Printf ("ProcessMonitor::%s() reg %s: 0x%" PRIx64, __FUNCTION__,
                      m_reg_name, data);
}

How can I make the Printf visible?

Thanks

log enable [-STgnpstv] [-f <filename>] <log-channel> <log-category>
[<log-category> [...]]

If you don't specify a "-f <filename>" you'll see the log output on stdout:

(lldb) b main
Breakpoint 1: where = ls`main + 9 at ls.c:166, address = 0x0000000000403069
(lldb) log enable freebsd process
(lldb) run
Process 29265 launching
ProcessFreeBSD::UpdateThreadList (pid = 29265)
ProcessFreeBSD::UpdateThreadList new tid = 102295
Process 29265 stopped
(lldb) process 29265 resuming (continue)
...

"log list" shows the available channels and categories.

Note that the "posix" channel (for POSIX_LOG_* categories) is spelled
"freebsd" or "linux", depending on your OS.
