MBCS_FORMAT_ITI_BUFFER_ Procedure
specifies the optional start mode of the formatting operation. When this parameter
has a value of 1, the formatting operation begins in the 1-byte mode. When this
parameter has a value of 2, the formatting operation begins in the 2-byte (MBCS)
mode. If any other value is specified, or if this parameter is not used, the starting
mode is determined from the source string content. This parameter can be used to
force a start in MBCS mode for a string that begins with Kanji double-spaces. This
is the only known ambiguous condition that might require the use of this parameter.
Consideration
Determining the size of the destination buffer is the responsibility of the calling
procedure.
