Hi,
I installed the Libsocket TCP library yesterday (from the
http://www.geocities.com/SiliconValley/Lab/3216/lsck.htm libsocket
pages) and noticed the resit demo crashing every time.
So, being the newbie I am and investigating the c code, I found this:
(resit.c)
int main (int argc, char *argv[])
{
struct hostent *hpke;
char *x;
... (snip)
printf ("Aliases: ");
while ( *(hpke->h_aliases ) ) {
printf ("%s ", *hpke->h_aliases ); <-----------Here
hpke->h_aliases ++;
}
... <snip rest>
as hpke is already a pointer, *hpke would dereference it, and force the
program to use the value at (*hpke) as a pointer to h_aliases, or am I
gravely mistaking here?
Shouldn't the correct code be:
printf ("Aliases: ");
while ( *(hpke->h_aliases ) ) {
printf ("%s ", hpke->h_aliases );
hpke->h_aliases ++;
}
My apologies if this has been signalled before,
Michiel Uitdehaag
