I'm trying to list all open sockets and their PIDs on Solaris 10 in C++.
In Solaris 11, they made this really simple by adding the PID to the mib structs (example, tcpConnCreationProcess in inet/mib2.h). This functionality isn't in Solaris 10, and can be seen in the new netstat source code.
In Solaris 10, I'm trying to use the KVM interface to get this information. Now I have the exact opposite problem where I can get the PIDs and fds without a problem, but getting the actual socket seems to be difficult.
According to some reading, the vnode struct contains the socket object (sonode?).
Is there an easy way to go from where I am to getting the socket information?
Hello,
I actually try to make client-server program.
I'm using SCO OpenServer Release 5.0.0 and when I try to compile my code (by TELNET) I've got this error :
I'm just using this simple code :

Hi,

Hi all,
On the server side, one socket is used for listening, the others are used for communicating with the client.
My question is: if i want to set option for socket, which socket should be set on?
If either can be set, what's the different?
Again, what's the different if set option... (1 Reply)
Hey, I'm new to the bsd kernel and i'm implementing a vop_read function. The problem I'm having is determining
1. Which physical block is being read given the vnode's logical block #
2. How many bytes are being read
Any tips are greatly appreciated! (0 Replies)

I need clarification on whether it is okay to set socket options on a listening socket

kvm_read
kvm_read(3KVM) Kernel VM Library Functions kvm_read(3KVM)NAME
kvm_read, kvm_write - copy data to or from a kernel image or running system
SYNOPSIS
cc [ flag... ] file... -lkvm [ library...]
#include <kvm.h>
ssize_t kvm_read(kvm_t *kd, uintptr_t addr, void *buf, size_t nbytes);
ssize_t kvm_write(kvm_t *kd, uintptr_t addr, void *buf, size_t nbytes);
DESCRIPTION
The kvm_read() function transfers data from the kernel image specified by kd (see kvm_open(3KVM)) to the address space of the process.
nbytes bytes of data are copied from the kernel virtual address given by addr to the buffer pointed to by buf.
The kvm_write() function is like kvm_read(), except that the direction of data transfer is reversed. To use this function, the
kvm_open(3KVM) call that returned kd must have specified write access. If a user virtual address is given, it is resolved in the address
space of the process specified in the most recent kvm_getu(3KVM) call.
USAGE
The kvm_read() and kvm_write() functions are obsolete and might be removed in a future release. The functions described on the
kvm_kread(3KVM) manual page should be used instead.
RETURN VALUES
On success, these functions return the number of bytes actually transferred. On failure, they return -1.
