Client applications and service providers
WORD FAR *pwCarry
[in] A FILETIME structure that contains the first unsigned 64-bit integer to be added.
[in] A FILETIME structure that contains the second unsigned 64-bit integer to be added.
[in, out, optional] On input, a pointer to the incoming carry flag. On output, a pointer to the carry result for the addition. This parameter can be NULL if the carry result is not required.
FtAdcFt function returns a FILETIME structure that contains the sum of the two integers. The two input parameters remain unchanged. If pwCarry is non-NULL, it contains the carry result for the sum, either 0 or 1.
FtAdcFt function is identical to FtAddFt when pwCarry is NULL. If pwCarry is not NULL and points to 0, FtAdcFt returns the same FILETIME value that FtAddFt returns.
