PFIND(9) Kernel Developer's Manual PFIND(9) NAME pfind, zpfind -- locate a process by number SYNOPSIS #include <sys/param.h> #include <sys/proc.h> struct proc * pfind(pid_t pid); struct proc * pfind_any(pid_t pid); struct proc * pfind_any_locked(pid_t pid); DESCRIPTION pfind() takes a pid as its argument and returns a pointer to the proc structure whose PID is specified in the argument only if the pid is on the allproc list. pfind_any() takes a pid as its argument. pfind_any() searches the allproc list and returns the first process whose PID matches and whose state is PRS_ZOMBIE. pfind_any_locked() is similar to pfind_any() ,but it does not lock the process hash bucket for the given pid. Instead, it asserts the corre- sponding process hash bucket is already locked. All three functions pfind(), pfind_any(), and pgfind_any_locked() lock the proc structure before returning. RETURN VALUES pfind(), pfind_any(), and pfind_any_locked() return pointer to a proc structure on success or NULL on failure.
