/**
This function allows the caller to request the current
configuration for one or more named elements. The resulting
string is in <ConfigAltResp> format. Any and all alternative
configuration strings shall also be appended to the end of the
current configuration string. If they are, they must appear
after the current configuration. They must contain the same
routing (GUID, NAME, PATH) as the current configuration string.
They must have an additional description indicating the type of
alternative configuration the string represents,
"ALTCFG=<StringToken>". That <StringToken> (when
converted from Hex UNICODE to binary) is a reference to a
string in the associated string pack.
@param[in] This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
@param[in] Request A null-terminated Unicode string in
<ConfigRequest> format. Note that this
includes the routing information as well as
the configurable name / value pairs. It is
invalid for this string to be in
<MultiConfigRequest> format.
@param[out] Progress On return, points to a character in the
Request string. Points to the string's null
terminator if request was successful. Points
to the most recent "&" before the first
failing name / value pair (or the beginning
of the string if the failure is in the first
name / value pair) if the request was not
successful.
@param[out] Results A null-terminated Unicode string in
<ConfigAltResp> format which has all values
filled in for the names in the Request string.
String to be allocated by the called function.
@retval EFI_SUCCESS The Results string is filled with the
values corresponding to all requested
names.
@retval EFI_OUT_OF_RESOURCES Not enough memory to store the
parts of the results that must be
stored awaiting possible future
protocols.
@retval EFI_INVALID_PARAMETER For example, passing in a NULL
for the Request parameter
would result in this type of
error. In this case, the
Progress parameter would be
set to NULL.
@retval EFI_NOT_FOUND Routing data doesn't match any
known driver. Progress set to the
first character in the routing header.
Note: There is no requirement that the
driver validate the routing data. It
must skip the <ConfigHdr> in order to
process the names.
@retval EFI_INVALID_PARAMETER Illegal syntax. Progress set
to most recent & before the
error or the beginning of the
string.
@retval EFI_INVALID_PARAMETER Unknown name. Progress points
to the & before the name in
question. Currently not implemented.
