AnalysisLibErrType XX_Dist (double xx, int degreesOfFreedom, double *probabilityXX);
Approximates the one-sided probability:
p = prob(X xx)
where X is a random variable from the 
2-distribution with the specified degrees of freedom
double x, p;
int n;
x = -123.456;
n = 6;
XX_Dist (x, n, &p);
/* Now p = 0 because chi-square distributed variables are non-negative. */
