const char *dmi_slot_width_name(dmi_slot_width_t value);Description
The dmi_slot_width_t enumeration tells the width of the data bus of a system
slot: a number of bits for parallel buses such as PCI, a number of lanes for
serial links such as PCI Express. It is the type of the bus_width,
base_bus_width and physical_width fields of dmi_slot_t, and of the
bus_width field of dmi_slot_peer_group_t. For PCI Express, the electrical
width is the widest link the slot supports; the width of the link actually
trained is not recorded in SMBIOS.
The dmi_slot_width_name function returns the name of a value, as the command
line tool shows it.
Values
DMI_SLOT_WIDTH_UNSPEC-
Unspecified.

DMI_SLOT_WIDTH_8_BIT-
8 bits.
DMI_SLOT_WIDTH_16_BIT-
16 bits.
DMI_SLOT_WIDTH_32_BIT-
32 bits.
DMI_SLOT_WIDTH_64_BIT-
64 bits.
DMI_SLOT_WIDTH_128_BIT-
128 bits.
DMI_SLOT_WIDTH_1X-
One lane (x1).
DMI_SLOT_WIDTH_2X-
Two lanes (x2).
DMI_SLOT_WIDTH_4X-
Four lanes (x4).
DMI_SLOT_WIDTH_8X-
Eight lanes (x8).
DMI_SLOT_WIDTH_12X-

Return value
dmi_slot_width_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.
