The IsDBCSLeadByte function determines whether a character is a lead byte

that is, the first byte of a character in a double-byte character set (DBCS).

BOOL IsDBCSLeadByte(

BYTE TestChar	// character to test
);

Parameters
TestChar

Specifies the character to be tested.

Return Values
If the character is a lead byte, the return value is nonzero.

If the character is not a lead byte, the return value is zero. To get extended error information, call GetLastError.

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 IsDBCSLeadByte function uses the ANSI code page to check lead-byte ranges.
