KINFO_GETPROC(3)	    Library Functions Manual	      KINFO_GETPROC(3)

NAME
       kinfo_getproc --	function for getting process information from kernel

LIBRARY
       System Utilities	Library	(libutil, -lutil)

SYNOPSIS
       #include	<sys/types.h>
       #include	<sys/user.h>
       #include	<libutil.h>

       struct kinfo_proc *
       kinfo_getproc(pid_t pid);

DESCRIPTION
       This  function  is used for obtaining process information from the ker-
       nel.

       The pid field contains  the  process  identifier.   This	 should	 be  a
       process	that you have privilege	to access.  This function is a wrapper
       around sysctl(3)	with the KERN_PROC_PID mib.  While the kernel  returns
       a  packed structure, this function expands the data into	a fixed	record
       format.

RETURN VALUES
       On success the kinfo_getproc() function returns a pointer to  a	struct
       kinfo_proc  structure  as defined by <sys/user.h>.  The pointer was ob-
       tained by an internal call to malloc(3) and must	be freed by the	caller
       with a call to free(3).	On failure the	kinfo_getproc()	 function  re-
       turns NULL.

SEE ALSO
       free(3),	malloc(3), sysctl(3)

HISTORY
       The kinfo_getproc() function first appeared in FreeBSD 7.0.

FreeBSD	13.2			 May 10, 2020		      KINFO_GETPROC(3)
