PROC_FIND(9)               Kernel Developer's Manual              PROC_FIND(9)

NAME
     proc_find, pgrp_find - find process or process group

SYNOPSIS
     #include <sys/proc.h>

     struct proc *
     proc_find(pid_t pid);

     struct pgrp *
     pgrp_find(pid_t pgid);

     extern kmutex_t *proc_lock;

DESCRIPTION
     The proc_find() and pgrp_find() functions retrieve process and process
     group structures from process ID pid and process group ID pgid.  Both
     functions must be called by holding a mutex(9) on proc_lock.

RETURN VALUES
     Upon successful completion, the described functions return a pointer to
     either struct proc or struct pgrp.  Otherwise, if the requested ID was
     not found, NULL is returned.
