This helper function is to be called by drivers to map configuration strings

|
|
|
|
@param This A pointer to the EFI_HII_CONFIG_ROUTING_PROTOCOL
|
|
instance.
|
|
@param ConfigResp A null-terminated Unicode string in <ConfigResp>
|
|
format.
|
|
@param Block A possibly null array of bytes representing the
|
|
current block. Only bytes referenced in the
|
|
ConfigResp string in the block are modified. If
|
|
this parameter is null or if the *BlockSize
|
|
parameter is (on input) shorter than required by
|
|
the Configuration string, only the BlockSize
|
|
parameter is updated and an appropriate status
|
|
(see below) is returned.
|
|
@param BlockSize The length of the Block in units of UINT8. On
|
|
input, this is the size of the Block. On output,
|
|
if successful, contains the largest index of the
|
|
modified byte in the Block, or the required buffer
|
|
size if the Block is not large enough.
|
|
@param Progress On return, points to an element of the ConfigResp
|
|
string filled in with the offset of 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) or the
|
|
terminating NULL if all was successful.
|
|
|
|
@retval EFI_SUCCESS The request succeeded. Progress points to the null
|
|
terminator at the end of the ConfigResp string.
|
|
@retval EFI_OUT_OF_RESOURCES Not enough memory to allocate Config. Progress
|
|
points to the first character of ConfigResp.
|
|
@retval EFI_INVALID_PARAMETER Passing in a NULL for the ConfigResp or
|
|
Block parameter would result in this type of
|
|
error. Progress points to the first character of
|
|
ConfigResp.
|
|
@retval EFI_INVALID_PARAMETER Encountered non <BlockName> formatted name /
|
|
value pair. Block is left updated and
|
|
Progress points at the '&' preceding the first
|
|
non-<BlockName>.
|
|
@retval EFI_BUFFER_TOO_SMALL Block not large enough. Progress undefined.
|
|
BlockSize is updated with the required buffer size.
|
|
@retval EFI_NOT_FOUND Target for the specified routing data was not found.
|
|
Progress points to the "G" in "GUID" of the errant
|
|
routing data.
