Description

The dmi_slot_type_t enumeration tells the bus or the form factor of a system slot, and is the type of the type field of dmi_slot_t. The specification assigns no values from 0x29 to 0x2F, from 0x31 to 0x9F, 0xB7, and above 0xC6.

PCI Express types which give a generation only are meant for slots whose physical width is their electrical width, the bus_width field of dmi_slot_t giving both. Types which also give a width are meant for slots wider than their electrical width: the type gives the physical width, and bus_width the electrical one.

The dmi_slot_type_name function returns the name of a value, as the command line tool shows it.

Return value

dmi_slot_type_name returns the name of the value, or nullptr if the value has no name. The name is in English, or translated to the locale set with dmi_set_locale when the library is built with localization support and has a translation of it. The string must not be modified or freed; a translated one stays valid until the locale is changed.

Errors

None.
