Hi, in my system (2.6.34-gentoo-r2), "man cerf" gives me the description of a certain complex error function. This function however is nowhere to be found. I tried this on 5 other linux boxes with the same result. May be the function was taken out at some point but the documentation stayed. Here is a minimum test file which can be saved as "test.c" and complied as gcc test.c -lm ------ #include <math.h> #include <complex.h> #include <stdio.h> int main (void){ double complex b,c; b=I*0.2; c=cerf(b); printf("%f + i%f\n",creal(c),cimag(c)); } ------ regards, Ozgur, -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
