on 4.0.0, ppc-darwin I don't see this problem.
On x86-cygwin 3.4.4 I do, but I don't think it has anything to do with map, or
net, or anything.
Consider the following program below. It prints:
bat:bat
on x86-cygwin 3.4.4
and
bat:zat
on ppc-darwin current CVS
inet_ntoa returns a char* to a fixed internal buffer which contains the decoded
net string. You are calling this function twice in one statement, and if you
print the pointers you are returned you'll find (or at least I find, and I can't
see how it could be otherwise) that these pointers are identical.
Now another question, which I'm not 100% certain at the moment and am happy to
have input on, is what about output this program should give, or if it is
undefined.
#include <iostream>
char foo[10]="cat";
char* writestring()
{
foo[0]='b';
return foo;
}
char* write2()
{
foo[0]='z';
return foo;
}
int main(void)
{ std::cout << writestring() << ":" << write2() << std::endl; }
