gcc 2.2.5 online manual contains bug in gethostbyname_r example

[Bossom, John]

Hi,

I was tracking down some documentation on gethostbyname_r and was staring at the
example on the document (link provided below) and noticed a coding error...

The example declares a local instance of "struct hostent hostbuf" and at the bottom
of the routine, it returns the pointer "hp" that had been returned by gethostbyname_r;
however, this pointer simply contains the address of the struct passed into hostbuf...
Hence, it is returning a pointer to a stack based variable which is immediately
invalid upon returning from the routine....

Cheers,
John E. Bossom
