localtime vs localtime_s and appropriate input arguments

Question

time_t rawtime;
struct tm * timeinfo;
time ( &rawtime );
timeinfo = localtime ( &rawtime );

This returns: warning C4996: \'localtime\': Thi

Answer 1

localtime_s is just a microsoft implementation of the localtime functon, you can safely keep using locatime becaue it's C++ ISO compliant and ony microsoft marked it as "deprecated". The localtime function itself isn't deprecated at all in the C++ world.

The localtime_s reference says that these parameters should be passed to it:

_tm 
Pointer to the time structure to be filled in.
 time 
Pointer to the stored time.
