Isn't strtod supposed to deal with NAN's?
I ran:
$ cat test3.c
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
int main(int argc,char **argv)
{
double num;
char *input="NAN";
char *border1="/////////////////////////////";
char *input2="inf";
char *border2="/////////////////////////////";
char **ptr;
num=strtod(input,ptr);
printf("num=%g\n",num);
printf("errno=%ld\n",errno);
printf("ptr=%p, points to %s\n",*ptr,*ptr);
num=strtod(input2,ptr);
printf("num=%g\n",num);
printf("errno=%ld\n",errno);
printf("ptr=%p, points to %s\n",*ptr,*ptr);
exit(0);
}
$
and I get a SIGSEGV in the first strtod call.
the manpage for strtod implies, to me, that it should deal with it.
Thanks!
