Question

When i debug a programmer, I found too many lines useless info which appear in GDB. this kind of infomation may come from iphone framework. it is not logged by my code. the info like this

Node 48 TrialMT(102,102,101,101)

Node 58 TrialMT(102,102,101,101)

Node 69 TrialMT(102,102,101,101)

Node 72 TrialMT(102,102,101,101)

Just too much. so i can not find my log.

I want to known is there a way i can export GDB log to a file, so i can find my log info in the file later on.

thanks

In Xcode you can type GDB commands in the debugger console. There you can reset the stdout and stderr file descriptors to your preferred log file like this

(gdb) call (void)close(1)
(gdb) call (void)close(2)
(gdb) call (int)open("/tmp/out.log", 0x201, 0644)
$1 = 1
(gdb) call (int)dup(1)
$2 = 2
(gdb) continue
