NAME
pfind, zpfind — locate a process by numberSYNOPSIS
#include < sys/param.h>#include < sys/proc.h>
struct proc *
pfind( pid_t pid);
struct proc *
zpfind( 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.zpfind() takes a pid as its argument. If zpfind() finds a process whose PID is equal to that of argument and is a zombie process, meaning that it must reside on the zombproc list, zpfind() returns a pointer to that proc structure.
Both pfind() and zpfind() lock the proc structure that is returned using PROC_LOCK( p).
RETURN VALUES
pfind() and zpfind() return a pointer to a proc structure on success and a NULL on failure.SEE ALSO
