--==========53BD2A4CBBAC142EBCDC========== Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: quoted-printable Content-Disposition: inline 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=3D"NAN"; char *border1=3D"/////////////////////////////"; char *input2=3D"inf"; char *border2=3D"/////////////////////////////"; char **ptr; num=3Dstrtod(input,ptr); printf("num=3D%g\n",num); printf("errno=3D%ld\n",errno); printf("ptr=3D%p, points to %s\n",*ptr,*ptr); num=3Dstrtod(input2,ptr); printf("num=3D%g\n",num); printf("errno=3D%ld\n",errno); printf("ptr=3D%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.
