Java How to use we use int64?
Recently my project needs int64 variables. However my os and computer are both 32bits.
So how can i use int64 as a parameter in a function.
and is int64 a structure as user-defined structures.....
???

Code:
#include <stdint.h>

int64_t e uint64_t.

On a 32 bit machine it is usually defined as (glibc code)

Code:
typedef unsigned long long int  uint64_t;

The compiler will probably use two registers to contain the data.

Hope it helps.

you could create a structure with two integer and typedef as unit64,
but the operation you are doing on this data types should be done through some function

like
int64 a = 100 /* will not work */

int64 a;
setValue(&a,..);


for all the operation you need to write the funcitons.because it not a ADT like int.
