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