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 kernel.

     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 obtained
     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 returns NULL.

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

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

FreeBSD ports 15.quarterly	  May 10, 2020			KINFO_GETPROC(3)
