MyProcPid is an int, so %d is the natural choice. the sys_types.h
manpage says:
* blksize_t, pid_t, and ssize_t shall be signed integer types.
and also: The implementation shall support one or more programming environments in which the widths of
blksize_t,pid_t, size_t, ssize_t, and susec‐ onds_t are no greater than the width of type long.
I wonder if we could just adopt pid_t for PIDs.
