i wouldn't recommend that, really, for a variety of reasons, including:
- generally only servers, and then only some of them, write lock files
- not all programs put their PID there
- if the program forks/execs or is multithreaded[1] you won't get an accurate
PID
in other words, this is not a reliable mechanism. just do what pidof does. the
code in busybox is like 100 lines long. =)
[1] unless you are using NTLP and have it set up correctly
