sctp_getassocid -- return an association id for a specified socket address.
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
sctp_assoc_t
sctp_getassocid(int s, struct sockaddr *addr);
DESCRIPTION
The sctp_getassocid() call attempts to look up the specified socket address addr and find the respective association identification.
RETURN VALUES
The call returns the association id upon success and 0 is returned upon failure.
ERRORS
The sctp_getassocid() function can return the following errors:
[ENOENT] The address does not have an association setup to it.
[EBADF] The argument s is not a valid descriptor.
[ENOTSOCK] The argument s is not a socket.

SCTP_CONNECTX(3) BSD Library Functions Manual SCTP_CONNECTX(3)NAME
sctp_connectx -- connect an SCTP socket with multiple destination addresses
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int
sctp_connectx(int sd, struct sockaddr *addrs, int addrcnt, sctp_assoc_t *id);
DESCRIPTION
The sctp_connectx() call attempts to initiate an association to a peer SCTP endpoint. The call operates similarly to connect() but it also
provides the ability to specify multiple destination addresses for the peer. This allows a fault tolerant method of initiating an associa-
tion. When one of the peers addresses is unreachable, the subsequent listed addresses will also be used to set up the association with the
peer.
The user also needs to consider that any address listed in an sctp_connectx() call is also considered "confirmed". A confirmed address is
one in which the SCTP transport will trust is a part of the association and it will not send a confirmation heartbeat to it with a random
nonce.
If the peer SCTP stack does not list one or more of the provided addresses in its response message then the extra addresses sent in the
sctp_connectx() call will be silently discarded from the association. On successful completion the provided id will be filled in with the
association identification of the newly forming association.
RETURN VALUES
The call returns 0 on success and -1 upon failure.
ERRORS
The sctp_connectx() function can return the following errors:
[EINVAL] An address listed has an invalid family or no addresses were provided.
[E2BIG] The size of the address list exceeds the amount of data provided.
[EBADF] The argument s is not a valid descriptor.
[ENOTSOCK] The argument s is not a socket.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
