SmbiosMiscAddRecord()

EFI_STATUS SmbiosMiscAddRecord	(	IN UINT8 *	Buffer,
		IN OUT EFI_SMBIOS_HANDLE *SmbiosHandle	OPTIONAL
	)

Adds an SMBIOS record.

Parameters

Buffer	The data for the SMBIOS record. The format of the record is determined by EFI_SMBIOS_TABLE_HEADER.Type. The size of the formatted area is defined by EFI_SMBIOS_TABLE_HEADER.Length and either followed by a double-null (0x0000) or a set of null terminated strings and a null.
SmbiosHandle	A unique handle will be assigned to the SMBIOS record if not NULL.

Return values

EFI_SUCCESS	Record was added.
EFI_OUT_OF_RESOURCES	Record was not added due to lack of system resources.
EFI_ALREADY_STARTED	The SmbiosHandle passed in was already in use.
