KINFO_GETALLPROC(3) FreeBSD Library Functions Manual KINFO_GETALLPROC(3)
NAME
kinfo_getallproc - function for getting process information of all
processes from kernel
LIBRARY
System Utilities Library (libutil, -lutil)
SYNOPSIS
#include <sys/types.h>
#include <sys/user.h>
#include <libutil.h>
struct kinfo_proc *
kinfo_getallproc(int *cntp);
DESCRIPTION
This function is used for obtaining process information of all processes
from the kernel.
The cntp field is a pointer containing the number of process structures
returned. This function is a wrapper around sysctl(3) with the
KERN_PROC_PROC mib. While the kernel returns a packed structure, this
function expands the data into a fixed record format.
RETURN VALUES
On success the kinfo_getallproc() function returns a pointer to cntp
struct kinfo_proc structures 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_getallproc() function
returns NULL.
SEE ALSO
free(3), malloc(3), sysctl(3)
HISTORY
The kinfo_getallproc() function first appeared in FreeBSD 8.3.
