I don't know the best way but the only(might be for me) way I came across
was to use *ps* command, which gives the information about running processes
on the system.
You can use system("ps  -A -o your_format_you_want_data_in") and write it to
a file using freopen() in C/C++ code.
Rest depends on how much you are familiar with string manipulation ;)
