Description

The dmi_memory_device_type_t enumeration tells the type of memory a memory device is made of, and is the type of the memory_type field of dmi_memory_device_t. The values 0x15 to 0x17 are reserved; the hidden enumerators DMI_MEMORY_DEVICE_TYPE_UNASSIGNED_START and DMI_MEMORY_DEVICE_TYPE_UNASSIGNED_END bound them.

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

Return value

dmi_memory_device_type_name returns the name of the value, or nullptr if the value has no name. The name is translated to the current locale when the library is built with localization support and has a translation for it, and is in English otherwise. The string is owned by the library and must not be modified or freed.

Errors

None.

Standards

DMTF SMBIOS Specification (DSP0134), version 2.1 or newer.
