KINFO_GETPROC(3) BSD 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 <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.
