FsRtlIsLeadDbcsCharacter function

The FsRtlIsLeadDbcsCharacter macro determines whether a character is a lead byte (the first byte of a character) in a double-byte character set (DBCS).

Syntax


BOOLEAN FsRtlIsLeadDbcsCharacter(
  _In_  UCHAR DbcsCharacter
);

Parameters

DbcsCharacter [in]

The character to be tested.

Return value

TRUE if the character is a lead byte, FALSE otherwise.

Remarks

Lead bytes are unique to double-byte character sets. A lead byte introduces a double-byte character. Lead bytes occupy a specific range of byte values. The FsRtlIsLeadDbcsCharacter macro uses the system code page to check lead-byte ranges.
