How to write a double type into file in c/c++ in windows?

double Time;
...
WriteFile( tmp_pip开发者_StackOverflow社区e, Time, sizeof(double), &dwWritten, NULL );

The above reports :

error C2664: 'WriteFile' : cannot convert parameter 2 from 'double' to 'LPCVOID'

You want &Time, not Time, for parameter 2 of the function call.
