/** | |
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. | |
