This function create a new string in String Package or updates an existing

string in a String Package. If StringId is 0, then a new string is added to
|

|
a String Package. If StringId is not zero, then a string in String Package is
|
||||||
|
updated. If SupportedLanguages is NULL, then the string is added or updated
|
||||||
|
for all the languages that the String Package supports. If SupportedLanguages
|
||||||
|
is not NULL, then the string is added or updated for the set of languages
|
||||||

specified by SupportedLanguages.

String Package associated with HiiHandle. If

is updated in the String Package associated

with HiiHandle.

@param[in] String A pointer to the Null-terminated Unicode string
|

to add or update in the String Package associated
|
||||||
|
with HiiHandle.

@param[in] SupportedLanguages A pointer to a Null-terminated ASCII string of

language codes. If this parameter is NULL, then

String is added or updated in the String Package

|
associated with HiiHandle for all the languages

HiiHandle for the set oflanguages specified by

@retval 0 The string could not be added or updated in the String Package.
