GETNUCRED(2)                  System Calls Manual                 GETNUCRED(2)

NAME
       getnucred  -  obtain  the  credentials  that  correspond  to  the given
       endpoint.

SYNOPSIS
       #include <sys/socket.h>
       #include <sys/ucred.h>

       int getnucred(endpoint_t proc_ep,  struct uucred * ucred);

DESCRIPTION
       Given an endpoint proc_ep, this function will fill in  ucred  with  the
       pid, uid, and gid that correspond to that endpoint.

RETURN VALUES
       On  success,  this  function returns 0 and ucred will be filled in.  On
       error, -1 is returned and errno is set.

ERRORS
       [EFAULT]       The address pointed to by ucred is not in a  valid  part
                      of  the process address space.  [EPERM] The user calling
                      this function has insufficient privileges. Only  a  user
                      with  an  euid of 0 may call this function.  [ESRCH] The
                      endpoint was not found. This is  caused  by  an  invalid
                      endpoint  or  an  endpoint  for a process that no longer
                      exists.
