KINFO_GETALLPROC(3) BSD 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 <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.
