dmi_hardware_security
Synopsis
#include <opendmi/entity/hardware-security.h>
typedef struct dmi_hardware_security {
dmi_hardware_security_status_t front_panel_reset;
dmi_hardware_security_status_t admin_password;
dmi_hardware_security_status_t keyboard_password;
dmi_hardware_security_status_t poweron_password;
} dmi_hardware_security_t;Description
The dmi_hardware_security_t structure holds the decoded hardware security
structure (type 24) of SMBIOS: the state of the passwords and of the front
panel reset, which the firmware sets for the whole system.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(hardware_security) and lives as long as the context it has been
decoded in.
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_entity_t *entity = dmi_registry_lookup_first(registry,
DMI_TYPE(hardware_security), true);
dmi_hardware_security_t *security = dmi_entity_info(entity,
DMI_TYPE(hardware_security));
if (security != nullptr) {
const char *state =
dmi_hardware_security_status_name(security->poweron_password);
printf("Power-on password: %s\n", state != nullptr ? state : "?");
