NAME

       pam_set_data, pam_get_data - PAM routines to maintain module specific state

SYNOPSIS

       [ flag ... ] file ...  [ library ... ]

DESCRIPTION

       and  allow  PAM service modules to access and update module specific information as needed.  These functions should not be used by applica-
       tions.

       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.  module_data_name should be unique across all services (UNIX, etc).

       The cleanup function is used to free any memory used by the data after it is no longer needed, and is invoked by The cleanup function takes
       as its arguments a pointer to the PAM handle, pamh, a pointer to the actual data, data, and a status code, pam_end_status.  The status code
       determines exactly what state information needs to be purged, and is therefore specific to each module.

       If is called and module data already exists under the same module_data_name (from a prior call to then the existing data is replaced by the
       new data, and the existing cleanup function is replaced by the new cleanup 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.

APPLICATION USAGE

       Refer to pam(3) for information on thread-safety of PAM interfaces.

RETURN VALUES

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

       No module specific data is present.
