-                    successful.
-
-  @param Results    A null-terminated Unicode string in
-                    <MultiConfigAltResp> format which has all values

+

+  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 This       Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.

+

+  @param 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.

+                    If a NULL is passed in for the Request field,

+                    all of the settings being abstracted by this function

+                    will be returned in the Results field.  In addition,

+                    if a ConfigHdr is passed in with no request elements,

+                    all of the settings being abstracted for that particular

+                    ConfigHdr reference will be returned in the Results Field.

+

+  @param 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 Results    A null-terminated Unicode string in

+                    <MultiConfigAltResp> 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_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

+  Build response packet according to TLS state machine. This function is only valid for

+  alert, handshake and change_cipher_spec content type.

+

+  The BuildResponsePacket() function builds TLS response packet in response to the TLS

+  request packet specified by RequestBuffer and RequestSize. If RequestBuffer is NULL and

+  RequestSize is 0, and TLS session status is EfiTlsSessionNotStarted, the TLS session

+  will be initiated and the response packet needs to be ClientHello. If RequestBuffer is

+  NULL and RequestSize is 0, and TLS session status is EfiTlsSessionClosing, the TLS

+  session will be closed and response packet needs to be CloseNotify. If RequestBuffer is

+  NULL and RequestSize is 0, and TLS session status is EfiTlsSessionError, the TLS

+  session has errors and the response packet needs to be Alert message based on error

+  type.

+

+  @param[in]       This           Pointer to the EFI_TLS_PROTOCOL instance.

+  @param[in]       RequestBuffer  Pointer to the most recently received TLS packet. NULL

+                                  means TLS need initiate the TLS session and response

+                                  packet need to be ClientHello.

+  @param[in]       RequestSize    Packet size in bytes for the most recently received TLS

+                                  packet. 0 is only valid when RequestBuffer is NULL.

+  @param[out]      Buffer         Pointer to the buffer to hold the built packet.

+  @param[in, out]  BufferSize     Pointer to the buffer size in bytes. On input, it is

+                                  the buffer size provided by the caller. On output, it

+                                  is the buffer size in fact needed to contain the

+                                  packet.

+

+  @retval EFI_SUCCESS             The required TLS packet is built successfully.

+                                  This is NULL.

+                                  RequestBuffer is NULL but RequestSize is NOT 0.

+                                  Buffer is NULL if *BufferSize is not zero.

+  @retval EFI_BUFFER_TOO_SMALL    BufferSize is too small to hold the response packet.

+  @retval EFI_NOT_READY           Current TLS session state is NOT ready to build
