SCTP_GETPADDRS(3)					   BSD Library Functions Manual 					 SCTP_GETPADDRS(3)

NAME

     sctp_getpaddrs, sctp_getladdrs -- return a list of addresses to the caller

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/socket.h>
     #include <netinet/sctp.h>

     int
     sctp_getpaddrs(int s, sctp_assoc_t asocid, struct sockaddr **addrs);

     int
     sctp_getladdrs(int s, sctp_assoc_t asocid, struct sockaddr **addrs);

DESCRIPTION

     The sctp_getpaddrs() function is used to get the list of the peers addresses.  The sctp_getladdrs() function is used to get the list of the
     local addresses.  The association of interest is identified by the asocid argument.  The addresses are returned in a newly allocated array of
     socket addresses returned in the argument addrs upon success.

     After the caller is finished, the function sctp_freepaddrs() or sctp_freeladdrs() should be used to release the memory allocated by these
     calls.

RETURN VALUES

     The call returns -1 upon failure and a count of the number of addresses returned in addrs upon success.

ERRORS

     The functions can return the following errors:

     [EINVAL]		An address listed has an invalid family or no addresses were provided.

     [ENOMEM]		The call cannot allocate memory to hold the socket addresses.

     [EBADF]		The argument s is not a valid descriptor.

     [ENOTSOCK] 	The argument s is not a socket.

NAME

       sctp_getpaddrs - Returns all peer addresses in an association.

SYNOPSIS

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_getpaddrs(int sd, sctp_assoc_t assoc_id,
			  struct sockaddr **addrs);

       void sctp_freepaddrs(struct sockaddr *addrs);

DESCRIPTION

       sctp_getpaddrs  returns	all peer addresses in an association. On return, addrs will point to a dynamically allocated packed array of sock-
       addr structures of the appropriate type for each address. The caller should use sctp_freepaddrs to free the memory. Note  that  the  in/out
       parameter addrs must not be NULL.

       If sd is an IPv4 socket, the addresses returned will be all IPv4 addresses. If sd is an IPv6 socket, the addresses returned can be a mix of
       IPv4 or IPv6 addresses.

       For one-to-many style sockets, id specifies the association to query. For one-to-one style sockets, id is ignored.

       sctp_freepaddrs frees all the resources allocated by sctp_getpaddrs.

RETURN VALUE

       On success, sctp_getpaddrs returns the number of peer addresses in the association. If there  is  no  association  on  this  socket,  0	is
       returned and the value of *addrs is undefined. On error, sctp_getpaddrs returns -1 and the value of *addrs is undefined.
