This function accepts a <MultiKeywordResp> formatted string, finds the associated
|
|
keyword owners, creates a <MultiConfigResp> string from it and forwards it to the
|
|
EFI_HII_ROUTING_PROTOCOL.RouteConfig function.
|
|
|
|
If there is an issue in resolving the contents of the KeywordString, then the
|
|
function returns an error and also sets the Progress and ProgressErr with the
|
|
appropriate information about where the issue occurred and additional data about
|
|
the nature of the issue.
|
|
|
|
In the case when KeywordString containing multiple keywords, when an EFI_NOT_FOUND
|
|
error is generated during processing the second or later keyword element, the system
|
|
storage associated with earlier keywords is not modified. All elements of the
|
|
KeywordString must successfully pass all tests for format and access prior to making
|
|
any modifications to storage.
|
|
|
|
In the case when EFI_DEVICE_ERROR is returned from the processing of a KeywordString
|
|
containing multiple keywords, the state of storage associated with earlier keywords
|
|
is undefined.
|
|
|
|
|
|
@param This Pointer to the EFI_KEYWORD_HANDLER _PROTOCOL instance.
|
|
|
|
@param KeywordString A null-terminated string in <MultiKeywordResp> format.
|
|
|
|
@param Progress On return, points to a character in the KeywordString.
|
|
Points to the string's NULL terminator if the 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 ProgressErr If during the processing of the KeywordString there was
|
|
a failure, this parameter gives additional information
|
|
about the possible source of the problem. The various
|
|
errors are defined in "Related Definitions" below.
|
|
|
|
|
|
@retval EFI_SUCCESS The specified action was completed successfully.
|
|
|
|
@retval EFI_INVALID_PARAMETER One or more of the following are TRUE:
|
|
1. KeywordString is NULL.
|
|
2. Parsing of the KeywordString resulted in an
|
|
error. See Progress and ProgressErr for more data.
|
|
|
|
@retval EFI_NOT_FOUND An element of the KeywordString was not found.
|
|
See ProgressErr for more data.

@retval EFI_OUT_OF_RESOURCES Required system resources could not be allocated.
