covert time_t ot LONG

[Programm3r]

what about type casting?

Regards Programm3r

thx for the quick rpl! I did type casting!! The compiler agrees on that! But is it really safe!!! It should not break at run-time. Also how much byte does LONG takeS?? thx!!

LONG is 4 bytes. time_t is now a 64-bit value (unless _USE_32BIT_TIME_T is defined).

i defined _USE_32BIT_TIME_T in the header file at the top!! I rebuild the solution. Still its showing time_t as type int_64 and size 8 bytes. where am I going wrong!

write this to know : std::cout << "sizeof(LONG) = " << sizeof(LONG) << endl;

Thx That is what i am doing to get the size!! I need to use 32bit time_t so i declered #define _USE_32BIT_TIME_T But its not making any diffence!! I am still getting 8 bytes as a size of time_t var.

am having problem coverting a time_t varible into LONG data type.

my Question is WHY?

hi alok!! I am porting code from VC6 to VC8. I have many other function which r taking LONg as a parameter. If I can convert the time_t to LONG, that will save time n efforts to change all those function. Thats why! thx

time_t is defined as __int64 by default!! How safe it is to declear var with __int32 instead of time_t so that i can get a 32 bit time.

typecast it to FILETIME ! it length is 64 bit!
