KINFO_GETPROC(3) FreeBSD 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.
