I'm writing a program to trace the tcp socket like trpt(8), I refer to Freebsd's trpt.c source code, which calls the following code to see tcp_debug and tcp_debx pointer location (definition in netinet/tcp_debug.h):

struct nlist nl[3];
nl[0].n_name = strdup("_tcp_debug");
nl[1].n_name = strdup("_tcp_debx");
if (nlist(syst, nl) < 0 || !nl[0].n_value)
...

But the n_name of "_tcp_debug" or "_tcp_debx" is invalid on AIX, who can tell me what's the n_name corresponding to the tcp_debug and tcp_debx on AIX ? Many thanks !

In addition, I can see the following output from kdb:

tcpdbg

---- TCP_DEBUG ----(@ F1000E0000C3BB00)----
(tcp_debx= 88)
...

'F1000E0000C3BB00' is I want to get through nlist via n_name.

Tried on linux, it didn't compile, due to lack of sys/protosw.h
Tried on Aix6.1, it didn't compile, due to lack of err.h

What platform did you use?
