Appends a formatted Unicode string to a Null-terminated Unicode string
This function appends a formatted Unicode string to the Null-terminated
Unicode string specified by String. String is optional and may be NULL.
Storage for the formatted Unicode string returned is allocated using
AllocatePool(). The pointer to the appended string is returned. The caller
is responsible for freeing the returned string.
If String is not NULL and not aligned on a 16-bit boundary, then ASSERT().
If FormatString is NULL, then ASSERT().
If FormatString is not aligned on a 16-bit boundary, then ASSERT().
@param[in] String A Null-terminated Unicode string.
@param[in] FormatString A Null-terminated Unicode format string.
@param[in] Marker VA_LIST marker for the variable argument list.
@retval NULL There was not enough available memory.
@return Null-terminated Unicode string is that is the formatted
string appended to String.
