+\r
+ @param VariableName A Null-terminated string that is the name of the vendor's variable.\r
+ Each VariableName is unique for each VendorGuid. VariableName must\r
+ contain 1 or more characters. If VariableName is an empty string,\r
+ then EFI_INVALID_PARAMETER is returned.\r
+ @param VendorGuid A unique identifier for the vendor.\r
+ @param Attributes Attributes bitmask to set for the variable.\r
+ @param DataSize The size in bytes of the Data buffer. Unless the EFI_VARIABLE_APPEND_WRITE, \r
+ EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS, or \r
+ EFI_VARIABLE_TIME_BASED_AUTHENTICATED_WRITE_ACCESS attribute is set, a size of zero \r
+ causes the variable to be deleted. When the EFI_VARIABLE_APPEND_WRITE attribute is \r
+ set, then a SetVariable() call with a DataSize of zero will not cause any change to \r
+ the variable value (the timestamp associated with the variable may be updated however \r
+ even if no new data value is provided,see the description of the \r
+ EFI_VARIABLE_AUTHENTICATION_2 descriptor below. In this case the DataSize will not \r
+ be zero since the EFI_VARIABLE_AUTHENTICATION_2 descriptor will be populated). \r
+ @param Data The contents for the variable.\r
+\r
+ @retval EFI_SUCCESS The firmware has successfully stored the variable and its data as\r
+ defined by the Attributes.\r
+ @retval EFI_INVALID_PARAMETER An invalid combination of attribute bits, name, and GUID was supplied, or the\r
+ DataSize exceeds the maximum allowed.\r
+ @retval EFI_INVALID_PARAMETER VariableName is an empty string.\r
+ @retval EFI_OUT_OF_RESOURCES Not enough storage is available to hold the variable and its data.\r
+ @retval EFI_DEVICE_ERROR The variable could not be retrieved due to a hardware error.\r
+ @retval EFI_WRITE_PROTECTED The variable in question is read-only.\r
+ @retval EFI_WRITE_PROTECTED The variable in question cannot be deleted.\r
+ @retval EFI_SECURITY_VIOLATION The variable could not be written due to EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS \r
+ or EFI_VARIABLE_TIME_BASED_AUTHENTICATED_WRITE_ACESS being set, but the AuthInfo \r
+ does NOT pass the validation check carried out by the firmware.\r
