Hi,
I am trying to locate how the “print” and “print fmt” statements work in bro scripts ; where are they implemented in source ? Specifically I am trying to determine if they always use stdout and stderr as inherited by src/main.cc
Any suggestions welcome !
Is this sort of what you’re looking for?
global my_file = open(“test.txt”);
event bro_init()
{
print my_file, “woo!”;
}

That is interesting , but it doesn’t really satisfy my curiosity Does the scripting I/O not use stderr + stdout ? I am interested in getting bro to redirect to syslog by inheriting file descriptors on startup .
Ah, ok. I didn’t understand where you are trying to get to in the end. It does use stdout if you don’t send the content off to a certain location. I take it that you have a script you’ve written that prints? I’m asking since Bro doesn’t print much to stdout or stderr by default I don’t immediately see the utility of redirecting those to syslog.
The implementation for the print statement can be found in Stmt.cc around line 259.

By default, print does go to stdout. The code is in src/Stmt.cc,
PrintStmt::DoExec().

Just to be sure, you know there's a builtin function syslog(msg),
right?
