The same way as with any C compiler, using the assert manual. I suggest
you get and read a decent C book such as K&R second edition and the
comp.lang.c FAQ.

void sumtounity(double *x, int N)
{
int i;
double tot = 0;

assert(N > 0);
assert(x != NULL);

for(i=0;i<N;i++)
tot += x[i];

assert(tot != 0.0);

for(i=0;i<N;i++)
x[i] /= tot;
}
