plz forgive me to put a C problem here; but the point is general!
i have written a code::
#include <stdio.h>
#include <stdlib.h>
int main()
{
int sys;
int i686;
sys=system("/bin/uname -m");
//printf ("%d",sys);
if (sys==i686){
printf("the syst. 32 bit");
}
else
printf("64but");
}
where i want the output of "system("/bin/uname -m")" as the variable
sys.....to find the machine structure.this procedure is not quite
working. can you people suggest me some way?

What are you comparing here? The i686 variable hasn't been initialized
to anything.

printf("the syst. 32 bit");
}
else
printf("64but");
}

Not working, or not doing what you expect? System() is supposed to
return the called app's exit code. If /bin/uname is successfully
launched and doesn't crash, that should be 0.

can you people suggest me some way?

I tried to find a standards-based solution to this, but for the life
of me I couldn't find a C++ streams equivalent to C's popen()
function. The closest I could find was to construct a Boost.Iostream
with a file descriptor opened with popen().

Did I miss something?
