Equivalent command of ltrace

Hi,

I want to find the exit status of a background process from another process.
I had earlier done this under Linux using ltrace . ltrace writes the exit
status of the background process to a file.

ltrace is not supported under Mac OS X (BSD). Is there any other system
command or system call that could do this?

You don't specify the relationship between the exiting process and the
querying process, nor any of the other details that would make it possible
to suggest one or more of the half dozen or so viable solutions to your
problem.

A short list might be:

- The wait* family of system calls.
- A pipe, socket or fifo.
- An entry in a file or directory.
- A shared memory segment or semaphore.
- A Mach message.
- An sh wrapper that writes $? into your logfile.

GI, GO.
