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.
