It's in /usr/include/sys/socketvar.h.  The problem is it also has that forward declaration.  So first up in that file we have:

extern struct free_sock_hash_bucket free_sock_hash_table[];

And then a bit later:

/*----------------------------------------------
//
// free_sock_hash_bucket
//
*/

#define FREE_SOCK_HASH_SZ   103

struct free_sock_hash_bucket
{
    int                 fsh_freecnt;
    simple_lock_data_t  fsh_lock;
    int                 fsh_intrlvl;
    struct socket       *fsh_freelist;
};

This is why I don't know that we can do anything about it other than work around it in our code.

Thanks!

   Unfortunately sys/socketvar.h is an AIX-supplied header file, so we can't change it.  I could open a bug report with IBM but even if they fix it in the future we still need to deal with this situation for this version.


Where is  struct free_sock_hash_bucket declared?
