Multiple sets of the three arguments can be specified to obtain the messages from more than one driver or module. http://www.verycomputer.com/174_880cb7f9fb72cc51_1.htm
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. When run in the foreground, the default is ignored and all errors are logged to stderr. Without knowing your system type and mosquitto version an answer will not be as precise as it could. ARGUMENTS The arguments, which must be specified in groups of three, are: mid Specifies the STREAMS module identification number from the streamtab entry.
Only one strace daemon or process at a time is permitted to open the STREAMS log driver as a trace logger. There was not a single line. I just don't know enough about Android to know if this is something I can even fix. The vendor has to provide some mechanism for determining license usage, but it's extremely limited.

Thank you! Or is this not an actual binary that you can path to on the system. Probably what happens is that the log file is created while the process has root privileges during startup but when it is deescalated to mosquitto it doesn't have permission to write And finally, /dev/tty stands for the controlling terminal (if any) for the current process.

Password Programming This forum is for all programming questions.

This option is equivalent to --verbose=0. -D, --debug [level] Increase or specify the debug output level. But I want to capture that number. By default, strace without arguments writes all STREAMS trace messages from all drivers and modules. You set the variable OUTPUT to be a command substitution which will execute whatever command you give it and take its output and set it to a variable.
I have tried few roms in xda here. On the other hand, I may be wrong. >> Can you run something like strace or valgrind to see what's happening >> before it crashes? > > Unfortunately no.

Maybe right maybe wrong i don't know.Anyway it gives some idea about the case. Perhaps this link will help you find your kernel's thread faster. FORMAT STREAMS trace event messages have the following format:
I can connect to my rooted device via adb shell and I see a logcat binary, but manually starting it gives me the error message as well: $ pwd / $ Problem: strace -ff fails on 2.4.21-rc1 8. http://forum.xda-developers.com/show....php?t=1196704 Hi skiddhard, Thanks for linking me the list.

So, this makes most of rooting ways malfunction. Running the strace command has the most impact on the timing of modules and drivers generating the trace messages that are sent to the strace process.
