Re: [Tinyos-help] help needed on uint64_t type

[Andrey Gursky]

Hi Bai!

I've tried it only in pure C (not nesC) with %lld and %llx.

Regards,
Andrey

Hi Andrey,

 

I just tested it. it didn't work though. What the flag you used in printf? Is that llx? Right? It still displayed low 32 bits. Confusing.

Bai

Bai, you should explicit write ULL at the end of the such big number (tested in C):
a=0x0000FFFFFFFFFFFFULL;

Hi All,

 

I have defined a uint64_t type variable as follows:

 

uint64_t a;

a=0x0000FFFFFFFFFFFF;

printf("a= %lld /n",a);

printf("a= %llx /n",a);

 

the result displayed as follows:

 

a= -1

a= ffffffff

 

The compilation didn't show any error. What is the problem? Does printf support to display the uint64_t type? Any help would be appreciated!

 

Regards,
Bai
