PAM_GET_DATA(3) 						 Linux-PAM Manual						   PAM_GET_DATA(3)

NAME

       pam_get_data - get module internal data

SYNOPSIS

       #include <security/pam_modules.h>

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

DESCRIPTION

       This function together with the pam_set_data(3) function is useful to manage module-specific data meaningful only to the calling PAM
       module.

       The pam_get_data function looks up the object associated with the (hopefully) unique string module_data_name in the PAM context specified
       by the pamh argument. A successful call to pam_get_data will result in data pointing to the object. Note, this data is not a copy and
       should be treated as constant by the module.

RETURN VALUES

       PAM_SUCCESS
	   Data was successful retrieved.

       PAM_SYSTEM_ERR
	   A NULL pointer was submitted as PAM handle or the function was called by an application.

       PAM_NO_MODULE_DATA
	   Module data not found or there is an entry, but it has the value NULL.
