- lpsz
Pointer to a null-terminated string or specifies a single character. If the high-order word of this parameter is zero, the low-order word must contain a single character to be converted. |
If the operand is a character string, the function returns a pointer to the converted string. Since the string is converted in place, the return value is equal to lpsz.
If the operand is a single character, the return value is a 32-bit value whose high-order word is zero, and low-order word contains the converted character.
There is no indication of success or failure. Failure is rare. |
