AIX Version 4.3 Kernel and Subsystems Technical Reference, Volume 1
raw_usrreq Kernel Service
Purpose
Implements user requests for raw protocols.
Syntax
#include <sys/types.h>
#include <sys/errno.h>
void raw_usrreq (so, req, m, nam, control)
struct socket *so;
int req;
struct mbuf *m;
struct mbuf *nam;
struct mbuf *control;
Parameters
so |
Identifies the address of a raw socket. |
req |
Specifies the request command. |
m |
Specifies the address of an mbuf structure containing data. |
nam |
Specifies the address of an mbuf structure containing the sockaddr structure. |
control |
This parameter should be set to a null value. |
Description
The raw_usrreq kernel service implements user requests for the raw protocol.
The raw_usrreq service supports the following commands:
PRU_ABORT |
Aborts (fast DISCONNECT, DETACH). |
PRU_ACCEPT |
Accepts connection from peer. |
PRU_ATTACH |
Attaches protocol to up. |
PRU_BIND |
Binds socket to address. |
PRU_CONNECT |
Establishes connection to peer. |
PRU_CONNECT2 |
Connects two sockets. |
PRU_CONTROL |
Controls operations on protocol. |
PRU_DETACH |
Detaches protocol from up. |
PRU_DISCONNECT |
Disconnects from peer. |
PRU_LISTEN |
Listens for connection. |
PRU_PEERADDR |
Fetches peer's address. |
PRU_RCVD |
Have taken data; more room now. |
PRU_RCVOOB |
Retrieves out of band data. |
PRU_SEND |
Sends this data. |
PRU_SENDOOB |
Sends out of band data. |
PRU_SENSE |
Returns status into m. |
PRU_SOCKADDR |
Fetches socket's address. |
PRU_SHUTDOWN |
Will not send any more data. |
Any unrecognized command causes the panic kernel service to be called.
The raw_userreq kernel service can be called from either the process or interrupt environment.
Return Values
EOPNOTSUPP |
Indicates an unsupported command. |
EINVAL |
Indicates a parameter error. |
EACCESS |
Indicates insufficient authority to support the PRU_ATTACH command. |
ENOTCONN |
Indicates an attempt to detach when not attached. |
EISCONN |
Indicates that the caller tried to connect while already connected. |
Implementation Specifics
The raw_userreq kernel service is part of Base Operating System (BOS) Runtime.
