pam_open_session(3PAM)					       PAM Library Functions					    pam_open_session(3PAM)

NAME

       pam_open_session, pam_close_session - perform PAM session creation and termination operations

SYNOPSIS

       cc [ flag ... ] file ... -lpam [ library ... ]
       #include <security/pam_appl.h>

       int pam_open_session(pam_handle_t *pamh, int flags);

       int pam_close_session(pam_handle_t *pamh, int flags);

DESCRIPTION

       The   pam_open_session()   function  is	called	after  a  user	has  been  successfully  authenticated.  See   pam_authenticate(3PAM)  and
       pam_acct_mgmt(3PAM).  It is used to notify the session modules that a  new  session   has  been	initiated.   All  programs  that  use  the
       pam(3PAM)  library  should  invoke  pam_open_session() when beginning a new session. Upon termination of this activity, pam_close_session()
       should be invoked to inform pam(3PAM) that the session has terminated.

       The pamh argument is an authentication handle obtained by a prior call to pam_start(). The following flag may be set in the flags field for
       pam_open_session() and pam_close_session():

       PAM_SILENT      The session service should not generate any messages.

RETURN VALUES

       Upon  successful  completion,   PAM_SUCCESS is returned.  In addition to the return values defined in pam(3PAM), the following value may be
       returned on error:

       PAM_SESSION_ERR	       Cannot make or remove an entry for the specified session.

NOTES

       In many instances, the pam_open_session() and pam_close_session() calls may be made by different processes. For example, in UNIX the  login
       process	opens  a  session,  while  the	init  process closes the session.  In this case, UTMP/WTMP entries may be used to link the call to
       pam_close_session() with an earlier call to pam_open_session(). This is possible because UTMP/WTMP entries are  uniquely  identified  by  a
       combination  of	attributes, including the user login name and device name, which are accessible through the  PAM handle, pamh. The call to
       pam_open_session() should precede  UTMP/WTMP entry management, and the call to pam_close_session() should follow   UTMP/WTMP  exit  manage-
       ment.

       The interfaces in  libpam are MT-Safe only if each thread within the multithreaded application uses its own  PAM handle.
