0xFFFFFFFF ?????

[Scott Wolfington]

Hi!

Does anyone know what the "& 0xFFFFFFFF" is doing
in this C statement? ft is a FILETIME type. qwResult
is a 64 bit integer (quadword in C). Thanks in advance!

ft.dwLowDateTime = (DWORD) (qwResult & 0xFFFFFFFF );

Taken from MSKB article: http://support.microsoft.com/support.../Q188/7/68.ASP

It is performing a logical AND function... it is a fast way to extract the lower 32 bits of a larger variable. Another technique to achieve the same task is to use the MOD function, but the value would need to be (&H0FFFFFFFF + 1).
