 NAME    [Toc]    [Back]
      pam_open_session, pam_close_session - perform PAM session creation and
      termination operations

 SYNOPSIS    [Toc]    [Back]
      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    [Toc]    [Back]
      pam_open_session() is called after a user has been successfully
      authenticated (refer to pam_authenticate(3) and pam_acct_mgmt(3)) and
      is used to notify the session modules that a new session has been
      initiated.  All programs that use the pam(3) 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(3)
      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.

 APPLICATION USAGE    [Toc]    [Back]
      Refer to pam(3) for information on thread-safety of PAM interfaces.

 RETURN VALUES    [Toc]    [Back]
      Upon successful completion, PAM_SUCCESS is returned.  In addition to
      the return values defined in pam(3), the following value may be
      returned on error:

      PAM_SESSION_ERR       Can not make/remove an entry for the specified
                            session.
