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
void FsRtlIsLeadDbcsCharacter(
DBCS_CHAR
);
Parameters
DBCS_CHAR
The character to be tested.
Return value
None
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.
