sprintf uint64_t in Linux

Question

In Linux I need to sprintf uint64_t This is how it defined in "stdint.h"

typedef unsigned long int   uint64_t;

What should i pass to sprintf?

Does [this Q/A](http://stackoverflow.com/questions/5140871/sprintf-for-unsigned-int64) apply at all? — admdrew, Sep 15 '14 at 19:27

The header <inttypes.h> defines macros to be used with the *printf and *scanf functions for the types defined in <stdint.h>.

To format a uint64_t value in decimal:

uint64_t n = ...;
sprintf(str, "%" PRIu64, n);

The PRIu64 macro expands to a string literal, which is concatenated with the "%" to form a valid format string.
