pam_get_data(3pam)

pam_set_data(3PAM)           PAM Library Functions          pam_set_data(3PAM)

NAME
       pam_set_data,  pam_get_data  - PAM routines to maintain module specific
       state

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

       int pam_set_data(pam_handle_t *pamh,
            const char *module_data_name, void *data,
            void (*cleanup) (pam_handle_t *pamh, void *data,
            int pam_end_status));


       int pam_get_data(const pam_handle_t *pamh,
                            const char *module_data_name, const void **data);

DESCRIPTION
       The pam_set_data() and pam_get_data() functions allow PAM service  mod‐
       ules  to access and update module specific information as needed. These
       functions should not be used by applications.


       The pam_set_data() function stores module specific data within the  PAM
       handle  pamh.  The  module_data_name  argument  uniquely identifies the
       data, and the data  argument  represents  the  actual  data.  The  mod‐
       ule_data_name argument should be unique across all services.


       The  pam_set_data()  function  may  register  a  cleanup function to be
       called during pam_end(3PAM) processing. The cleanup function should  do
       whatever  is  appropriate based on pam_end_status, the status passed to
       pam_end() by  the  application.  Any  allocated  memory  for  the  mod‐
       ule_data_name must be freed.


       If pam_set_data() is called and module data already exists from a prior
       call  to  pam_set_data()  under the same module_data_name, the existing
       cleanup function is called with a pam_end_status  of  PAM_SUCCESS,  the
       existing  data  is  replaced  by the new data, and the existing cleanup
       function is replaced by the new cleanup function.


       The pam_get_data() function retrieves module-specific  data  stored  in
       the  PAM handle, pamh, identified by the unique name, module_data_name.
       The data argument is assigned the address of the  requested  data.  The
       data  retrieved  by pam_get_data() should not be modified or freed. The
       data will be released by pam_end().

RETURN VALUES
       In addition to the return values listed  in  pam(3PAM),  the  following
       value may also be returned:

       PAM_NO_MODULE_DATA    No module specific data is present.


ATTRIBUTES
