Re: [Q] Tracefile Conversion

Have a look at:

http://www.research.att.com/~breslau/vint/trace.html

It has a pointer to a C program that does the ascii to
binary conversion.  The reverse conversion should be a 
pretty simple modification.

Dear Seniors

I'm trying to convert ~ns/tcl/ex/example-trace to normal ascii file. 

Below code is my first workout, and it seems not working. The result is so big.
(first field is time and next field is size)
 
What's wrong ?

And If you have converter programs(that is, from ascii to bin and bin to ascii)
can I have a copy of it ?

Thanks

int main(int argc, char *argv[])
{
        unsigned int time;
        unsigned int size;
        int pos;
        FILE *file;
        file=fopen(argv[1],"r");
        for(pos=0;pos<10;pos++)
        {
                fread(&time,4,1,file);
                fread(&size,4,1,file);
                printf("%10u %10u\n",htonl(time), htonl(size));
        }
}
