I am sending this mail again with some more information abt my tries! i m trying to write a module to create a proc entry to show tcp statistics. i have included linux/module.h, linux/proc_fs.h and net/tcp.h in the module. my kernel is 2.2.16. tcp.h has declared the structure tcp_statistics defined in net/snmp.h. it is of return type tcp_mib. tcp_statistics is defined as an EXPORT_SYMBOL(tcp_statistics) in linux/net/netsyms.c. i dunno what am i missing as the above layout works perfectly fine if i replace tcp with ip but does not work if i use net_statistics. any type of help will be appreciated. thanks, phoram mehta - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
