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.March 1, 2013 | FreeBSD |
