Function AddUnicodeString2

MdePkg/Library/UefiLib/UefiLib.c:1088–1244

This function adds the Null-terminated Unicode string specified by UnicodeString to UnicodeStringTable. If Language is a member of SupportedLanguages then UnicodeString is added to UnicodeStringTable. New buffers are allocated for both Language and UnicodeString. The contents of Language and UnicodeString are copied into these new buffers. These buffers are automatically freed wh
