ltrace - A library call tracer ltrace "[-diLS] [-a column] [-s strsize] [-o filename] command [arg ...]" ltrace is a program that simply runs the specified command until it exits. It intercepts and records the dynamic library calls which are called by the executed process and the signals which are received by that process.

Its use is very similar to strace(1).

-a column Align return values in a secific column (default column 50). -d Increase the debugging level.

-f Trace child processes as they are created by currently traced processes as a result of the fork(2) or clone(2) system calls. The new process is attached as soon as its pid is known.

-i Print the instruction pointer at the time of the library call.

-s Specify the maximum string size to print (the default is 32).

-L DON'T display library calls (use it with the -S option).

-S Display system calls as well as library calls

-o filename Write the trace output to the file filename rather than to stderr.

At the moment, there are too many bugs to list here.

If you like to report a bug, send a notice to the author, or use the bug(1) program if you are under Debian GNU/Linux.
