Sample a process on Mac OS X from a C/C++ program

The Sample Process feature in Activity Monitor is quite a useful thing. However, I need to do the same thing (take samples) of a certain process from another running process (C/C++) or a command line.

Is there any way to do this? I have been googling for this since a few days without any luck.

Solution

  • There is a command-line utility sample.

    Example:

    sample Safari -file /dev/stdout

    It will get exactly the same output with Activity Monitor.
