RC_FIND_PIDS(3)		    System Manager's Manual	       RC_FIND_PIDS(3)

NAME
     rc_find_pids — finds the pids of processes that match the given criteria

LIBRARY
     Run Command library (librc, -lrc)

SYNOPSIS
     #include <rc.h>

     RC_PIDLIST *
     rc_find_pids(const char *const *argv, const char *cmd, uid_t uid,
	 pid_t pid);

DESCRIPTION
     rc_find_pids() returns RC_PIDLIST, a structure based on the LIST macro
     from queue(3) which contains all the pids found matching the given crite‐
     ria.  If pid is given then only that pid is returned if it is running.
     Otherise we check all instances of argv with a process name of cmd owned
     by uid, all of which are optional.

     The returned list should be freed when done.

IMPLEMENTATION NOTES
     On BSD systems we use Kernel Data Access Library (libkvm, -lkvm) and on
     Linux systems we use the /proc filesystem to find our processes.

     Each RC_PID should be freed in the list as well as the list itself when
     done.

SEE ALSO
     free(3), queue(3)
