pam_putenv(3PAM)					       PAM Library Functions						  pam_putenv(3PAM)

NAME

       pam_putenv - change or add a value to the PAM environment

SYNOPSIS

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

       int pam_putenv(pam_handle_t *pamh, const char *name_value);

DESCRIPTION

       The   pam_putenv()  function sets the value of the PAM environment variable name equal to value either by altering an existing PAM variable
       or by creating a new one.

       The name_value argument points to a string of the form name=value. A call to pam_putenv() does not immediately change the environment.  All
       name_value  pairs  are  stored  in the PAM handle pamh. An application such as  login(1) may make a call to  pam_getenv(3PAM) or pam_geten-
       vlist(3PAM) to retrieve the PAM environment variables saved in the PAM handle and set them in the environment if  appropriate.  login  will
       not  set  PAM environment values which overwrite the values for	SHELL, HOME, LOGNAME, MAIL, CDPATH, IFS, and  PATH. Nor will login set PAM
       environment values which overwrite any value that begins with  LD_.

       If name_value equals  NAME=, then the value associated with  NAME in the PAM handle will be set to an empty value.   If	name_value  equals
       NAME, then the environment variable  NAME will be removed from the PAM handle.

RETURN VALUES

       The pam_putenv() function may return one of the following values:

       PAM_SUCCESS	  The function returned successfully.

       PAM_OPEN_ERR	  dlopen() failed when dynamically loading a service module.

       PAM_SYMBOL_ERR	  Symbol not found.

       PAM_SERVICE_ERR	  Error in service module.

       PAM_SYSTEM_ERR	  System error.

       PAM_BUF_ERR	  Memory buffer error.

       PAM_CONV_ERR	  Conversation failure.

       PAM_PERM_DENIED	  Permission denied.

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.
